I can reliably reproduce a TransactionError in zodb.storage.tests.testmemory
in testPackWhileWriting in MinimalMemoryTests. It does not occur every
time, but when I run the tests in a loop, I get that error in less than
30 seconds.
$ python2.2 test.py -Lvv test_memory testPackWhileWriting
[...]
testPackWhileWriting (<class 'zodb.storage.tests.test_memory.FullMemoryTest=
s'>) ... ok
