I haven't seen the hang again.  I went back to 30.0.92 on Dec 21, after
hacking up a script that uses emacsclient to invoke view-lossage.
(Rather than bisecting by changes to the code, at 4 weeks per iteration,
I thought it might be more effective to try a bisection strategy based
on the flow of data through Emacs.  Depending on what view-lossage tells
me--assuming I ever see the hang again--, I can add hacky logging code
to my builds in whatever place seems appropriate.  FWIW, prior to going
back to 30.0.92, I diffed the changes from 30.0.91 to 30.0.92 and
nothing seemed plausible as a possible cause.)

At this point, I'm fine with calling the bug very rare and moving on.
If it happens again, I'll see what information I can get and update the
bug report.
