Thanks. I'll take a look at glibc. Any feel for how widely available it is across *nixes?

If thread-switching performance is really critical, and pthreads are too slow,

You've got the wrong end of the stick. It isn't the pthreads or threads that are too slow, it is threads::shared.

Vis. Using Thread::Queue (which uses threads::shared and its cond vars and mutexes), the best throughput I've achieved between two threads is about 50,000 scalars/second.

My current implementation is achieving (on Windows using event objects) 500,000 scalars/second reliably, and I've seen close to twice that.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
