I am trying to fix an issue with GNU emacs that is driving me insane
which is a severe slow-down (a hang of 10 seconds or more) whenever
I've loaded a large C++ buffer (100,000+ lines or more -- a file
autogenerated by swig).
The hang happens sporadically for no reason (no user action triggers
it) and happens even if the buffer is not being displayed.
It may be font-lock issue, but I am unsure how to limit font-lock to
parse only a couple of lines.
Can anyone help me out or suggest stuff to try?

Are you using CEDET / semantic? Is the file particularly nasty, such as
by having lots of code-generating macros (like, say
FOR_BLOCK(i, "asd") { .. }) which could confuse the parser?
Cheers,

Maybe (setq jit-lock-stealth-time nil)
