+ * Network timeouts.
+ * Because of the way this client is written it doesn't need to constantly talk (keep-alive) to the server to make 
+ * sure it is there. We detect a buggy / overloaded server by the call timeout. The default values will be ok for 
+ * nearly all cases. If they aren't the pool has most likely overload issues. Low call timeout values are preferable -
+ * long timeouts mean that we waste hashes on potentially stale jobs. Connection report will tell you how long the
+ * server usually takes to process our calls.
+ *
+ * call_timeout - How long should we wait for a response from the server before we assume it is dead and drop the connection.
+ * retry_time	- How long should we wait before another connection attempt.
+ *                Both values are in seconds.
+ * giveup_limit - Limit how many times we try to reconnect to the pool. Zero means no limit. Note that stak miners
+ *                don't mine while the connection is lost, so your computer's power usage goes down to idle.

+ * LARGE PAGE SUPPORT
+ * Large pages need a properly set up OS. It can be difficult if you are not used to systems administration,
+ * but the performance results are worth the trouble - you will get around 20% boost. Slow memory mode is
+ * meant as a backup, you won't get stellar results there. If you are running into trouble, especially
+ * on Windows, please read the common issues in the README.
+ *
+ * By default we will try to allocate large pages. This means you need to "Run As Administrator" on Windows.
+ * You need to edit your system's group policies to enable locking large pages. Here are the steps from MSDN
+ *
+ * 1. On the Start menu, click Run. In the Open box, type gpedit.msc.
+ * 2. On the Local Group Policy Editor console, expand Computer Configuration, and then expand Windows Settings.
+ * 3. Expand Security Settings, and then expand Local Policies.
+ * 4. Select the User Rights Assignment folder.
+ * 5. The policies will be displayed in the details pane.
+ * 6. In the pane, double-click Lock pages in memory.
+ * 7. In the Local Security Setting – Lock pages in memory dialog box, click Add User or Group.
+ * 8. In the Select Users, Service Accounts, or Groups dialog box, add an account that you will run the miner on
+ * 9. Reboot for change to take effect.
+ *
+ * Windows also tends to fragment memory a lot. If you are running on a system with 4-8GB of RAM you might need
+ * to switch off all the auto-start applications and reboot to have a large enough chunk of contiguous memory.
+ *
+ * On Linux you will need to configure large page support "sudo sysctl -w vm.nr_hugepages=128" and increase your
+ * ulimit -l. To do do this you need to add following lines to /etc/security/limits.conf - "* soft memlock 262144"
+ * and "* hard memlock 262144". You can also do it Windows-style and simply run-as-root, but this is NOT
+ * recommended for security reasons.
+ *
+ * Memory locking means that the kernel can't swap out the page to disk - something that is unlikely to happen on a
+ * command line system that isn't starved of memory. I haven't observed any difference on a CLI Linux system between
+ * locked and unlocked memory. If that is your setup see option "no_mlck".

+ * no_mlck - This option is only relevant on Linux, where we can use large pages without locking memory.
+ *           It will never use slow memory, but it won't attempt to mlock
