Second - I'm finishing boost.task-0.4.0 which replaces this_task::reschedule_until() by this_task::block(). block() suspends the current task without blocking the worker-thread. The blocked task gets rescheduled by the internal scheduler (returning from block()):

while ( ! condition) this_task::block();

Version 0.4.0 allows to synchronize or exchange messages between the tasks without deadlocking the threadpool (that means amount of tasks >> worker- threads in pool).

regards, Oliver

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.
