Thanks - I'll steer clear of using reschedule_until at the moment. Being
able to block a task without locking out the worker thread would be
useful for me, but I suspect my requirement may be rather different to
yours. I'm pretty much assuming amount of tasks == worker-threads in
pool. My main interest in a thread pool is to avoid creating and
destroying a new thread each time a task has to run but I suspect I may
use task or threadpool it this way initially and see what the overhead
is like.
