I just thought I would add some perspective.

* The MPEJXV9B problem (as I understand it) is limited to the
  Posix shell rm -R (recursive) command. MPE purges, with or
  without the ;TREE option and shell rm commands without the -R
  option are NOT effected.
* Therefore the MPEJXV9B problem is only a show stopper for a
  very specific subset of our users. I am very glad Mark pointed
  out the problem, and I agree that it is serious, particularly
  for Mark, but many/most customers would not be effected. This
  would include many/most customers that use Posix.
* Even if you are a Posix user, you can avoid installing MPEJXV9B
  easily by simply "veto"ing it in Patch/iX. If there is a problem
  with "veto"ing MPEJXV9B it has not been reported. If someone
  knows of a problem, please speak up.

I guess my general take on this issue is that it is not a very
good reason for most customers to avoid PP5. I am still glad that
Mark Bixby took the time to mention the problem and clarify it.
Thanks Mark.

NOTE: there have been some other issues mentioned here
that warrant consideration (w.r.t Oracle and one problem with
HPDATEDIFF). I personally feel like these other issues whould
weigh more heavily (on average) in deciding whether or not to
install PP5.

This is a pretty straigh forward workaround for most users (IMO).

This means, "veto the patch", not "avoid installing PP5" (IMO).
