emacs: "24.0.95.1"
fedora linux 16 x86_64
In shell mode:
rpm -qf /usr/lib64/pyth
then hit tab. cpu goes to 100%, emacs is unresponsive for a LONG time.
This problem seems to be new.
Seems to be triggered by rpm. Replacing with e.g., 'ls' doesn't seem to produce
the same symptoms.

Thanks for the report. This should really have gone to bug list though.
Anyway, it's doing `rpm -q -a', which can be slow, depending on your
system. It's dumb, in that:
it should probably give an explanatory message before running that command
it doesn't try to cache the result of this slow command in any way (cf
eg woman)
it should not actually be running this command when the "-f" argument is
used (compare with rpm -q -f TAB), it should be doing filename
completion
if you use `rpm -q -f', it does better, doing filename completion, but the
results it presents are all files, rather than just *.rpm files.

Also,
rpm -qa --nodigest --nosignature
would be much faster (0.25s for me versus 2s for rpm -qa).
But then you have to jump through the hoop of testing that those options
are supported. Maybe they are old enough to be taken for granted.

That was me being dumb, mixing up rpm -qf and rpm -qp.

Maybe all that is needed for now is:

Hopefully fixed in emacs-24 branch.
