I don't know if this is a bug, a feature of NFS, or if I'm just
overlooking something here, but the mkfifo shell command (and ultimately
the mkfifo system call) isn't letting me create a fifo on NFS mounted
filesystems as a normal user, even though I've write access to the
directory in which I'm trying to create the fifo.  The same operation
works fine when performed on the ffs filesystem on my RD54.  However, I
can create a fifo on NFS filesystems if I su to root.

The NFS server machine in this instance is OpenBSD/i386 2.1 (yeah yeah, I
know... At work I just don't have easy access to the same mass bandwidth
and easy transfer of bulk data to home anymore.  Otherwise I'd have that
machine loaded up with NetBSD/i386.)

I've included some basic command line stuff below to illustrate the
problem.  If necessary I can provide k(trace|dump) output as well from the
offending invocation of mkfifo.
