Put the NFS4 vop method for fifo's behind "#if 0" because it is unused.
Add a XXX comment to say that I think the unusedness is a bug.

for the new thread. The rest of the fields in the pcb wind up being
written to before they're read as a normal part of the pcb usage but
this field may be read upon return to userland, having it be uninitialized
garbage is bad.

This closes the last (known) race issues in ATA which should fix
the various hangs etc seen on heavy loaded systems.
Change from using timeout functions to using callout functions in
the timeout code. This together with above closes the race that could

Also fix the possible recursion in ata_reinit() on very dodgy

are stored in userland in libpthread.
There is a small race condition in this patch which could cause
problems if a signal arrives after setting the (kernel) signal
mask and before exec'ing. The thread's set of pending signals
also are not yet installed in the exec'd process. Both of these
will be corrected with the addition of a special syscall.
