Well, if keyboard input is a source of entropy (as I believe it is) it makes
sense typing "svnadmin create foo" on the command-line wouldn't suffer the
pause -- you just added entropy to the reservoir thereof. See if running
the tests (or some subset thereof) goes faster if you jiggle your mouse the
entire time the tests run.
