[Zope] HotFix? for commit_sub

...speaks about a new version to loose the problems with commit_sub when
uploading large files.
I can't just install a new version on our server, but a HotFix will do. Is
there one?

I know how to create my own HotFixes and I've looked at the difference in
the code in Transaction but a bit afraid of doing the right thing.
Some help please.
