Ah-ha, I think I see it: AtCommit_Memory releases memory in the blank
portal (by doing EndPortalAllocMode()). AtAbort_Memory forgets to do so.
Will commit this fix momentarily.

That is a relatively minor leak, compared to leaking *all* memory
allocated in the failed transaction, which is what it was doing until
now :-(. But I think I will fix it anyway ... the code is awfully
ugly, and it is still a leak.
