[ZODB-Dev] Inquiry: subtransaction commits w/ FileStorage

[sean.upton@uniontrib.com]

I'm running Zope 2.4.2 on Debian using FileStorage. Does anybody know where
subtransactions get saved/swapped to disk?  I'm trying to ascertain that
they are indeed getting committed to disk, and not just failing and keeping
everything in memory until the final commit.  I know that for me,
$INSTANCE_HOME/var/Data.fs.tmp gets written to before the final commit on
larger transactions, but I'm not sure where (or whether) subtransactions are
being saved to disk.  

My code looks like this:
      #numobjects is the number of objects to create.
      for i in range(int(numobjects)):
            recordID = str(i+1)
            obj=POSCirculationRecord(recordID)
            self._setOb(recordID, obj)
            obj = self._getOb(recordID)
            obj.index_object()
            if i%1000 == 0:
		   get_transaction().commit(1)

Any pointers would be appreciated.
Thanks,
Sean
