I do not understand why you want this (why must "write op #3"
be done in a separte transaction?).
But, when you *really* want it, make a redirect between "op #2" and "op #3".

On my Zope page, you will find an External Method "emulatedRedirect"
which may be helpful should do want to avoid a real redirect.
Be warned however, that its use may cause "op #1" and "op #2" to
be executed twice (in case of request retrial after "ConflictError").
