I moved off of the most recent dev branches for our "production" system and put them on the release version for 0.8.

This shouldn't be a problem unless your fetcher hangs on regex processing. This is relatively easy to check - pick up one of the remaining longer-running tasks and do a couple of thread dumps, you will see what occupies most of the time; if you can hook up a profiler in a fast-sampling mode then it's even better ...
-.*(/.+?)/.*?\1/.*?\1/. Andrzej , didn't you say awhile back when we were looking at regular expressions for a different stalling problem that you don't use these in your production systems?
True, I don't - I'm using only a combination of prefix/suffix filters. Prefix filters give me the domains of interest, and suffix filters give me (more or less) mime types I'm interested in. Any other border cases I can hardcode in a separate urlfilter, thus avoiding regexes completely.
