The other day, I investigated a bit why when often get

pthread_create: Resource temporarily unavailable

when unmounting a filesystem.  This message is produced by libpthread
because it didn't manage to allocate a stack.  It indeed gets a
EKERN_INVALID_ARGUMENT to its vm_allocate calls.  This is due to the
mach_task_self() port being invalid. This is due to the process actually
getting terminated: gnumach's task_terminate() indeed disables the task
port before terminating threads.  I tried to put ipc_task_disable()
after task_hold() and task_dowait(), like is done in xnu, but I'm still
getting the issue.  I haven't investigated further for now, I just
wanted to share my findings so far.
