RFH: testsuite Heisenbugs

[Thorsten Glaser]

Hi,

apparently I’m supposed to post here, not to cvs-dev, right?

Anyway, I’ve got sporadic issues running the testsuite: when
doing a “make check”, I get a failure; when I then re-start (-f)
the testsuite, the testcase in question works, and it aborts
at the next one, etc. (eventually, they all work). Also, this
only happens on my laptop (IBM X40, MirBSD), not on my dayjob
desktop (multi-GHz machine, Debian), despite same codebase.
This also only affects -r and -p modes.

The cases in question are:

- import-after-initial-6
  (nothing instead of 'original')

- sticky-23
  ('no longer pertinent' instead of 'was lost')

- client-9 (not in -p mode)
  (transcript follows)
        OK, whatever
        PASS: client-8

Now, I’m suspecting a timing issue or something, so if anyone
has got an idea why those particular tests (somewhat reliably)
fail, and how to fix them… we already have raised some timeouts
compared to the original sources; I attached a diff.

Thanks in advance,
