[Boost-users] [boost::thread] Problems with condition objects

Hi:

I'm having a bit of trouble with the implementation of the monitor
pattern by means of using mutex and condition classes.

I have a scheduler thread and a group of worker threads and the
scheduling algorithm waits until some worker notifies that it has done
the job.

It seems that the call to condition::notify_one() must be in a
specific order because if the worker calls notify_one before the
scheduler arrives to the waiting line it behaves as if the condition
object has lost the previous call to notify_one.

Is this behavior the one we must expect? and, if so, can any one share
a workaround.

Thanks in advance.

René
