Waiting on multiple semaphores at the same time
Hi,
Is it possible in Java to wait for multiple semaphores in one call? Like the waitformultipleobjects in win32. So I have multiple semaphores and i would like to be informed if one or more get signalled.

You could keep looping through the semaphores calling tryAcquire() until you acquire a permit in a particular semaphore? In the loop make it sleep for a 10ms or so as to not burn all the CPU.

Looping and testing for, say, 10ms would give a latency of (on average) 5ms. I could reduce the sleep-time but then more cpu would be used, slowing other programs down and requirering more power (on e.g. laptops).
