Hi all,

How often is method boost::interprocess::message_queue::receive signaled 
assuming there is data in the queue? Is it just at the end/beginning of a 
time-slice? I have been debugging a piece of code that is showing that receive 
is signaled at intervals of 15, 30 or 45 ms, and 15 ms is the duration of the 
time-slice of the of Windows OS when running on a multicore machine.

Is there a way to increase the priority of the thread that is blocked at a 
receive method in a way that it would be executed right after it's signaled? Or 
if not possible, what other mechanism could be used?

Thanks,

Andre
