[Boost-users] [statechart] Asynchronous Machines

If I have an asynchronous state machine running in another thread and
I send it an event, is there any way to have the sending thread block
until the event is processed?  I need to use an asynchoronous machine
because the rest of my app is threaded but yet there are points where
I must synchronize to know the machine is in a certain state before
moving on.

>From the documentation it seems like passing zero to
FifoWorker::operator() (via fifo_scheduler::operator()) will do the
trick, but I'm not sure.

I've created a non-blocking asynchronous machine because the
thread calling fifo_scheduler::operator() should not block if
the queue is empty.  It should process all events in the queue
and return.

Have I got that all correct?
