but if the thread waits (without any timeslices) for the cond_signal from the other thread, that would limit it to watching only 1 thread.

No, that is not so. The variable upon which the cond_wait() is waiting can be cond_signal()ed from any thread (that has a lock on the variable).

Also, if more than one thread are in a cond_wait() state on the same variable, one of them (non-determanistically) will be awoken.

You can also signal a variable using cond_broadcast(), in which case all threads currently blocking on that variable will be woken up, rather than just one.

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

In the absence of evidence, opinion is indistinguishable from prejudice.
