e82e3902	2011-07-27T16:40:52	If work has been cloned it is already at the head of the list and when being reinserted into the queue it should be placed back at the head of the list.
98f609b5	2011-07-27T10:31:44	Sanity check to prove locking.
1536e085	2011-07-26T20:48:05	Increase efficiency of slow mining threads such as CPU miners dramatically. Do this by detecting which threads cannot complete searching a work item within the scantime and then divide up a work item into multiple smaller work items. Detect the age of the work items and if they've been cloned before to prevent doing the same work over. If the work is too old to be divided, then see if it can be time rolled and do that to generate work. This dramatically decreases the number of queued work items from a pool leading to higher overall efficiency (but the same hashrate and share submission rate).
fa17f034	2011-07-26T11:58:45	Implement much more accurate rolling statistics per thread and per gpu and improve accuracy of rolling displayed values.
7707ed4d	2011-07-26T10:26:03	Add a menu to manage GPUs on the fly allowing you to enable/disable GPUs or try restarting them. Keep track of which GPUs are alive versus enabled. Start threads for devices that are even disabled, but don't allow them to start working.
