OK, I built an nsd (3.3 ad 13 to match andrew) w/o my patch. My man pages are indeed correct for my system [mandrake 8.0 with patches] -- I start it up, create/lock/destroy a mutex in a single nscp session, and get
nsthread(1175) error: ptread_mutex_destroy failed in NsMutexDestroy: Device or resource busy
Aborted
and nsd is dead.
[On my patched server, I was correct, it loops infinitely.]
