So we can pthread cancel a stuck thread, but can't pthread join it.
...
And we can't tq freeze the old queue or we could hang here.
And we need to re-initialise all the opencl contexts so send a test command and if it succeeds reinit the card.

Differentiate thread failure from GPU failure by declaring a GPU sick first and trying to restart the thread without re-initialising the card.
...
If that fails, then try once more at ten minutes and declare it dead.
This should prevent an attempted re-initialising of the GPU from taking out other GPUs.

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.

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).
