Hi,

Bodgitt and Scarper 2.1.1

"Any attempt to lock a resource that is already locked should cause the current thread to give up the CPU, consuming no CPU cycles until the desired resource becomes available."

I felt it was really bad to do this to a GUI user so my locking solution puts uses a lock request with a timeout. This puts the lock in a TIMED_WAIT rather than a WAIT state.

I'm pretty sure that consumes no CPU cycles but its not really blocking until the resource is available.

And of course now I'm about to submit and I'm in a flap about this.

Its says "should" rather than "must" which helps.

Does anyone have any good/bad experiences submitting this sort of approach?

Michael
