I agree that this is an issue.

I frequently find that I can do dpkg -S
*then* start up another window and manually type out a similar
line involving grep /var/lib/dpkg/info/*.list

and have the grep complete before the dpkg -S completes.

The machine I'm using at the moment is too fast for this, but the
difference is still signficant (~20x):

$ time grep dselect /var/lib/dpkg/info/*.list
real    0m0.059s
user    0m0.010s
sys     0m0.040s
$ time dpkg -S dselect
dpkg: /usr/bin/dselect
dpkg: /usr/man/man8/dselect.8.gz
real    0m1.262s
user    0m1.090s
sys     0m0.100s
