I am not sure if changing the priority of the finalizationProcess could possibly break something, and I also do not yet understand why changing the priority makes such a big difference both in Squeak and Pharo.

I think normal processes (with priority 40) could starve the finalization process if it's priority were <= 40 (#systemBackgroundPriority is 20).

That's true, I hadn't thought of that.

How should this issue be handled? Should I add this as issues to the bug tracking tools for Pharo and Squeak respectively?

I uploaded a fix to the Inbox: Collections-ul.362. If you're using a Trunk image, just update it and load this package to your image. If you're using a stock 4.1 image, then the easiest way to get the fix, is to add the following line to the end of WeakKeyDictionary >> #finalizeValues

cleanUpAfterRemove ifTrue: [ self fixCollisionsFrom: array size ]

If you have the time, please check if this fixes the issue for Squeak.

Unfortunately, this doesn't help with the deadlock issue. Cheers, Joachim Geidel
