Just to see if it is the finalization thing - have you tried finding
and killing the finalizationProcess and seeing if it still happens?

Seaside in particular makes extensive use (too much use, I think) of
WeakArray, which can sometimes turn out to be a real problem in
production - though the symptoms I've seen are of extremely high CPU
usage rather than outright hanging.
