For interest, on my 2.5year old i386 Ubuntu laptop, it takes

  ./bzr selftest notestnothing  6.07s user 0.21s system 46% cpu 13.438 total

with cold cache, and

  ./bzr selftest notestnothing  3.26s user 0.10s system 86% cpu 3.902 total

when warm.  I can see why you want it.

I think typing the full module name will get a bit tedious (and maybe
take more than 10 seconds sometimes, the first time you type it :-) so
I would rather it matched on a substring or regexp in the module name.
 Still the patch looks ok, so conditional +1 from me to merge it:

 * deserves a mention in news
 * should also get a mention in the HACKING section about how to run
the selftests

It seems like this might be useful when there are import-related
failures in the test suite, as well as the speed benefit.
