I also tried that commit(). Memory consumption still grows permanently.
Thanks for the report. Upon debugging this a little, there's indeed a
bug which crept in in pysqlite 2.2.1 because of incorrect usage of the
weak references (*). This leads to the list of weak references per
connection to always grow and never shrink. I'll try to provide a fix
real soon.

Fixed in Subversion. A pysqlite 2.3.1 release will follow during the next
days, which is the same code that will be in Python 2.5 beta1 btw.
