Using Linux with BerkeleyDB 4.7.25 the bsddb/test/test_replication.py
test is very flaky.  It alternately passes, raises an AssertionError
because of the timeout or gets a segmentation fault or bus error.

(side note: i updated test_replication to not use hard coded port numbers)

I have not tried this test using other BerkeleyDB versions.

Gregory, could you possibly try my svn, revision 529?

python 2.6b1+, bdb 4.7.25 on x86 ubuntu linux.

(that last comment was using pybsddb svn r529)

hmm.  nevermind.

those last results clearly used the wrong bsddb library.

Okay, now i've run the correct test suite on the correct modules with
pybsddb r530:

The problems still happen.  Sometimes it passes.  Other times it raises
an assertion error.

test01_basic_replication DBReplicationManger error:

line 134, in test01_basic_replication
    self.assertTrue(time.time()<timeout)

test01_basic_replication DBBaseReplication error:

line 342, in test01_basic_replication
    self.assertEquals("123", v)


and some others.

i haven't seen it segfault anymore though.

Are you using a python pydebug version?. Can you reproduce the issue
with a no "pydebug" python interpreter?

using a python trunk optimized (non-debug) build and pybsddb r530:

Greg, is this issue still pending?. Can we close it?.
