The work length in the miner thread gets smaller but doesn't get bigger if it's under 1 second.
...
This could end up leading to CPU under-utilisation and lower and lower hash rates.
Fix it by increasing work length if it drops under 1 second.

Dividing work is like the work is never removed at all so treat it as such. However the queued bool needs to be reset to ensure we *can* request more work even if we didn't initially.

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.

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).
