endless "g_main_context_{check,prepare} called recursively [...]"

[Josh Sled]

While in another window/app, not using emacs for a while, but with gnus
(v5.11) polling in the background for new mail over an imaps connection, I
often notice one cpu/core running full-out, spewing message-pairs to the
terminal as fast as it can draw them:

    (emacs:7259): GLib-WARNING **: g_main_context_check() called recursively 
from within a source's check() or prepare() member.

    (emacs:7259): GLib-WARNING **: g_main_context_prepare() called recursively 
from within a source's check() or prepare() member.

I believe I recall a previous instance of the bug's occurrence as being
seriously detrimental to performance, but the window would ultimately do
pieces of a refresh every many 10's of seconds.  In both cases, I need to
kill the process and restart.

I'll try to gdb attach to a future instance of the problem if it occurs.
