Nothing in the storage API reveals this.

Search the output of fsdump.py:

    http://zope.org/Wikis/ZODB/FileStorageBackup

for tid, and suck out the "oid=<number>" fields from following lines.

You could also look at the internal code executed by FileStorage.undo().

One way or another, you have to search the .fs file for the
transaction's record, then pick apart the data records the transaction
record contains.
