I doubt it will solve the hanging problem, but you could try

(setq progress-feedback-use-echo-area t)

in init.el to disable the progress bar.

All of this happens only when you're in the hung state, right?

The fact that you can call any XEmacs code at all suggests that the
Xt event loop is still running, and the high-priority callbacks
directly from the Xt event loop get run.  However, the Lisp event loop
is stuck, apparently.  I'm not sure how that can happen....

You don't say, so I'll check: you can't interrupt the hang with
repeated C-g?  (One may not be enough, but two or more should be.)

It sounds like one possibility is that there's either a bad regexp in
MH-E or the XEmacs regexp engine is broken.  Try setting fontlock to
"off" and see if that helps.

Is it possible to find out what the contents of "+inbox" are by doing
something like "C-x b junk RET C-x i +inbox RET" or "C-x b junk RET C-u
M-! some-mh-command RET"?

This isn't surprising, given that XEmacs is in a very odd state.  I
don't know that it means much, but I'm glad you report it.
