Try hitting <Ctrl-G> a few times and emacs should give up on whatever
it's crunching and return its undivided attention to you.  I'd be very
surprised if it actually hung itself, though it may seem that way on
occasion; I've worked on huge files with font-lock on, and never a
single lock-up, I only had to wait a few minutes for the initial buffer
fontification.  If your computer runs slow, and you don't want to wait
for emacs to scan the entire file when it's first loaded I seem to
recall something about a mode called lazy-lock-mode which might help.

Hope that helps,
  Karmix
