It works for me on NFS-mounted filesystems.  (Solaris 2.5.1 and SunOS
4.1.4.)  If FIFOs don't work on such filesystems, then that is a
serious bug in the operating system.

It is certainly sensible to perform the test on the same filesystem we
will actually use the FIFOs on.  But the fixed name in /tmp can cause
clashes if two people are configuring zsh at the same time.  I think
some attempt at a unique name is necessary.

It works on Solaris 2.5.1.  But of course we have /dev/fd, so the FIFOs
aren't required in any case.
