Latest cvs hangs in completion tests

[Peter Whaite <peta@xxxxxxxxxxxxxxxxx>]

I noticed this after the readonly patch (#14915) went in.   Pretty sure it was
ok before that. System is:
  
  % cat /etc/issue

  Red Hat Linux release 6.2 (mixed)
  Kernel 2.4.3 on an i686

  % uname -a
  Linux aragorn 2.4.3 #8 Mon Apr 30 19:05:32 EDT 2001 i686 unknown

Verbose test output:

  % ZTST_verbose=2 make test TESTNUM=Y 
  if test -n "gcc"; then \
    cd .. && \
    make MODDIR=`pwd`/Test/Modules install.modules > /dev/null; \
  fi
  for f in ./Y*.ztst; do \
    ../Src/zsh +Z -f ./ztst.zsh $f; \
  done
  ./Y01completion.ztst: starting.

Then hangs.  Note directory group is sticky which may be a bit unusual...

  % ls -ld comp.tmp

  % ls -lR comp.tmp

Let me know if other info is needed.
