[Maria-developers] Review of mysql-test-run speedup patch

Hi Serg, Can you review below patch? (sorry for no commit mail, I forgot to configure outgoing mail on my new laptop before committing). I was for a long time annoyed that mtr takes 20 seconds starting up before it starts running the first test. So being bored one evening I ran a Perl profiler on the code and fixed the culprit. (BTW, I haven't forgotten your suggestion to change include/long_test.inc information to be in a separate file instead; I just haven't gotten around to it yet.) - Kristian.
