ror, not on "normal" teardown condition (thread quit pipe
being closed). Flagging threads as being in error condition upon all
exit paths would lead to false "errors" sent to the client, which we
want to avoid, since the client could then think it needs to kill a

the "last" snapshot, so
we can do a time delta between the current and last snapshot to figure
out if we need to report the thread as stalled or not.

enqueue, 2% (performance improvement) for
dequeue. Overall number of operations (dequeue+enqueue) increased with
the patch.
We can verify that:
successful enqueues - successful dequeues = end_dequeues
For all runs (ensures correctness: no lost node).

n wfqueue without having to
have legacy code in our way: I plan to move all the legacy ABI to
wfqueue0.c, and have a fresh start in terms of ABI for the new wfqueue.
That way, we can eventually remove the wfqueue v0 ABI when we decide to
bump the library version number (and break compatibi
ze, which would break API compatibility. Any idea on how to
