The difference is that input-pending-p does polling (you have to keep
calling input-pending-p), whereas while-no-input is interrupt based (it
will stop whatever you're doing when the key comes in).

Might very well be: while-no-input does not by-itself let processes run.
I don't know what the CEDET code does, so I just mentioned
while-no-input as something related, but indeed it might not solve
our problem.

>> Then please go ahead and install your change.

Great, thank you,
