Ok then I guess this comment in Connection doesn't apply anymore:

# It sucks that we have to hold the lock to read _invalidated.
# Normally, _invalidated is written by calling dict.update, which
# will execute atomically by virtue of the GIL.  But some storage
# might generate oids where hash or compare invokes Python code.  In
# that case, the GIL can't save us.
