I'm not sure about the tsrm_new_thread_(begin/end)_handlers handlers though. Try and unlock the mutex call in TSRM.c before line 191 and re-lock it after that line.
    Since the deadlock was happening when
    tsrm_new_thread_begin_handler() was called, I've also added
    unlock/lock pairs around begin_handler and end_handler. Now,
    the deadlock does not happen anymore.

OK. I'm waiting for Zeev to take a look at the code as he wrote TSRM. I think we can probably narrow the whole ts_resource() down to one pair of lock/unlock which will be the right way to fix it, but adding those unlock/lock's will at least allow you to continue development.

    Btw, CVS on cvs.zend.com times out currently.

Yeah, it seems to be a network problem and not a problem with the host itself. Andi --- Andi Gutmans <andi@zend.com> http://www.zend.com/
