This used to say "nsubxcnt isn't decreased when subtransactions abort", but there's no variable called nsubxcnt. Commit 8548ddc61b changed it to "subxcnt", among other typo fixes, but that was wrong too: the comment actually talks about txn->nsubtxns. That's the field that's incremented but never decremented and is used for the allocation earlier in the function.
