Sorry to hear that. My tip (but you might already have heard that
countless times): Have emacs built with debugging info and attach gdb to
the process once it hangs. Produce a suitable backtrace (w/ the elisp
part) and post that to the list. Otherwise there is no way to know where
to look. :-(

Last but not least: And it is a real hang, so you cannot cancel it and
you need to really kill emacs? Could you give the master branch a try
and maybe also the patches I re-sent last week?

Good luck,
Matthias
