TempoaryStorage.py has a few tuning constants. The above error reads
as though RECENTLY_GC_OIDS_LEN is too small for your application. It
may well be that the default tuning of TempoaryStorage does not match
your application very well.
It would be useful to try FileStorage to help decide on where to focus
attention. If FileStorage behaves a lot better then that also suggests
that TempoaryStorage is miss-tuned for your application.
