The only danger here is if remote_hostio_close can throw.  However, this
was already a danger (in theory) before the patch -- there is a rule
(perhaps unwritten and/or unenforced) that one cannot throw during a
"do_cleanups".

I didn't look but some assurance that this can't happen would be good to
have.
