what happens if pulse is invoked before wait?

[Andy Fish]

Hi,

I'm using the Monitor class to perform some simple synchronization between
threads. In the documentation for pulse it says:

"The remarks for Wait(Object, Int32) address an issue that arises when Pulse
is invoked before Wait."

I can't find any reference to this issue anywhere. Can someone enlighten me
as to the nature of it?

TIA

Andy

Effectively, any Pulse or PulseAll which is called when no thread is
waiting on the monitor is a no-op. A monitor is *not* a counting
semaphore (although it can be used to build one).

Ok, thanks John. That's the behaviour I was expecting (infact relying on)
anyway.
