[Bro-Commits] [git/bro] fastpath: Fix memory leak in DNS TXT lookups. (62de567)

This might be a significant leak since local.bro has the MHR and notary scripts loaded by default now and those use TXT lookups. Though, the leak is when there's a request for something that's already cached locally, that might happen often enough (same file/cert seen multiple times).

Nice find. A large site that was having trouble on their workers is running that now. We should find out pretty soon.
