while-no-input is a more general and robust way to do what your (while (not
(input-pending-p))) is trying to do.  It's basically designed specifically
for cases like yours.  But it's a new feature in Emacs-22.

with-local-quit is just a convenient macro to temporarily disable
inhibit-quit (that's typically set in timers, post-command-hooks, ...).
The macro-expanded code doesn't use any new feature.  It's not a general
solution to your problem, but it can be used to solve the specific problem
of the OP where C-g wasn't able to unfreeze Emacs.

cd ...emacs/lisp; grep with-local-quit **/*.el

Read the definition of the macro: it's fairly simple.
