No, they won't exit pool_wrapper() while there are pending requests, but if that is a bug it is easy to fix. And by that description the wait I inserted after context_reset() in pool_wrapper() should not be there, since it releases ltp_mutex before the ID is removed from thread_keys[]. However another thread could be waiting in pool_pause() and start another pause. And the thread which did pool_resume() will be active and could call pool_pause() again (but I think it won't in the same LDAP operation with the current bconfig.c code). So if pool_wrapper() does not go active for context_reset() we must ensure that a pause is not started while a thread in pool_wrapper() is dying. That leaves thread_keys[] protected by either a pause or one of two mutexes, depending on circumstances. I'll sleep on it before trying to wrap my head around that one:-) >> (...)

Um, okay... could remove them from configure and tell anyone who needs them to shout. How about pool_context() called from subsystems which create their own threads (like Perl code or plugins)? I guess it's just that I don't see I why using a private, hopefully-OS-independent hack is an improvement over OS-provided thread-specific data (when that is supported). Any risk that there are systems around which support non-contiguous stacks? (Allocate a new stack chunk if the current one is used up, and chain it to the old one.) I don't have a clue how common they are or were, nor of the arguments for/against implementing them. -- Regards, Hallvard
