Re: Y03arguments.ztst fails

[Peter Stephenson <pws@csr.com>]

I'm seeing these failures in Y03arguments.ztst too, they don't seem to
be there in 4.1.1-test-1.  I would think it's more likely to be in the
functions than the C code, since no-one dares touch the latter.

I'm also getting random failures with multios tests which I haven't seen
before.  I don't think the underlying problem is new, I think it's the
same issue as this comment:

# Following two tests have to be separated since in
#   print bar >foo >bar && print "$(<foo) $(<bar)"
# the multios aren't flushed until after the substitutions take
# place.  This can't be right.

--- separating the tests doesn't actually fix the race.  I can insert a
`sleep' but it's a bit nasty.  Unfortunately, the multios have to be
asynchronous (or we end up with something like DOS's bizarre pipe
implementation) so this is pretty fundamental.
