Around Jan 13, the refleak hunting test that is reported on python-checkins started to report refleaks on virtually every run. I suspect this is due to r59944 (at 2008-01-13 16:29:41) which was from patch #1700288 to cache methods. With this patch it makes it much harder to spot refleaks. Does anyone have ideas how to fix it? The only one I have is to disable the cache with a special flag, env't variable, sys variable/function or the like. We could make this available only in debug mode. The cache should normally be enabled, but could be disabled solely on the refleak runs.

Suggestions?

Expose an API to clear the cache, and clear it at shutdown? It should probably be part of interpreter shutdown anyway.
