Gnus master unusable

Gnus master unusable

[James Cloos]

I tried upgrading last night.  What a time sink. :)

Bisecting took several hours; the result is:

Ever since that gnus gets stuck starting up.

I have a local leafnode as my primary; secondaries are one nnimap and
one nnmaildir.  (Gnus does not do any splitting.)

When it fails, emacs continues to poll(2) (or select(2) or whichever) on
its file decriptors, but does nothing else.

My secondary gnus, running on Julian's debian emacs-24-snapshot, has no
problems with its list of remote nntp and nnrss servers.

Reverting that single commit is a pain; the conflicts are significant.

I didn't see anything while poking around after a failed start which
could help debug this; only nnimap stuff, and that looked to be fine.

Is there at least some var to prevent async nntp?  The only servers are
leafnode and imapd on localhost, so async has little value on this box.
