The first problem is that I've been playing with the cond_* apis for quite a while now and basically, they do not seem to work properly. As best as I can assertain. But there are precious few examples of their use (from Perl) as far as I can find.

The second problem is that I am using emulations of those APIs rather than the real thing, so it's not clear to me whether the problems I have had are down to the APIs themselves, the Win32 emulations, or just the sparsity of documentation and my (lack of) understanding of how to use them.

The piece of the OPs puzzle that is still missing is: does the hang that occurs on single-cpu Win32 also happen on single-cpu Linux? Conversely, does the hang not happen on multi-cpu Win32?

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
