Hi,
We noticed that we can not build auctex on Tru64 Unix 5.1
(alphaev67-dec-osf5.1) because emacs-22.2 hangs. It also hangs with, for
example "M-! ls". This all works fine on the same machine with
emacs-21.4 (and also hangs with emacs-22.1)
Here is a backtrace of the hanging child:

Any ideas on what changed from 21.x to 22.x that could be causing this?
