Summary:                    Saving of admin file still doesn't work correctly
Description: 
On an update with
  pkgutil -U -u -y
I got after some package updates the error

...
Installation of <CSWpmipcshrlite> was successful.

pkgrm: ERROR: unable to open admin file </var/opt/csw/pkgutil/admin.run>:

Removal of <CSWpmiozlib> failed (internal error).
No changes were made to the system.

The error was with this version:

I just noticed that pkgutil leaves the admin.run file lots of times which
previously was no problem since it was just overwritten but now when I have
the "multiple instance"-protection it's a problem. One thing is to clean up
better before exiting but an unexpected (e.g. user aborted) exit can always
happen. I have therefor also added checks for other pkgutil processes when
an admin.run file is found, if only one process is running the file is
considered stale and removed which should work in most cases. This is in
r80.
