Call fc: 🧵 :quit() on thread destruction, and remove code that explicitly terminates threads from the destructors of the objects that own those threads.
...
Fix fc::thread to set the thread name in the Debugger when the name is set after thread construction.
When terminating a thread, cancel any tasks that have been schedule()d or async()ed but have not yet started executing.
When canceling a task blocked on a fc::mutex, notify the thread to reschedule the task to allow it to clean up the mutex's block list.
Fix a bug in managing the recursive lock count when tasks block on a fc::mutex
Reorder the code that manages the hard links for log files to avoid an exception generated by unlinking a locked file on Windows.

Schedule fibers in the order they are asynced or unblocked. Earlier behavior was always to start newly-asycned tasks before resuming existing tasks, so existing tasks could be starved if there was a steady stream of new tasks created. Now all tasks are started or resumed in the order they are created or unblocked.

When reusing a context, re-initialize most of its fields. This fixes at least two errors:
...
- we were canceling tasks that hadn't been canceled, because the canceled flag was left set to true and the next task assigned to the context then became canceled as soon as it yielded
- we were resumeing blocked tasks before they should have resumed, because their blocking_promises list wasn't cleared and they were unblocking because the erroneous promises were fulfilled
As a debugging aid, we also record the cancellation reason whenever a task is canceled, and include that in the canceled_exception (this is only enabled in debug builds)

Remove erroneous assert in fc::thread_d::check_for_timeouts()

I believe this assert was being triggered when the only task on
a thread did a fc::usleep (it might only have been when the
sleep was of very short duration).

Set minimum sleep time to 10ms to avoid potential race where the thread wakes back up immediately after being put on sleep queue. This can probably be reduced to about 2ms, but this just seemed safer for now (DanL suggested 10ms).

MAJOR BUG FIX - fc::usleep causing hang&leak
...
In certain cases when usleep is passed a small value, there is
a race condition that would cause the process to hang and then
when an attempt to quit the thread was made new contexts would
be allocated rapidly filling all available memory.
