Actually, this might have to do with the fix I committed to
test_threaded_import in r82885.
In order for test_threaded_import to work, we have to unload the "Guinea
pig" module before importing it from several threads at once. For
whatever reason, test_threaded_import uses random as its Guinea pig
module, which means random gets unloaded and reimported again.
But at this point, I must admit I don't even understand the failure
message. |
