Can we apply this patch for bug 84 and 425?

[joakim]

These bugs are both about hangs when emacs deals with external processes:
   http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=84
   http://emacsbugs.donarmstrong.com/cgi-bin/bugreport.cgi?bug=425

Markus Triska has a patch which reduces my experiences of the hang from
about once a day to not at all so far.

How can we proceed with this patch?
