Hi all!
Finally, I can not stand it any longer. So, I'm happy to present
multiprocessing support for iotests test runner.
testing on tmpfs:
Before:
time check -qcow2
...
real 12m28.095s
user 9m53.398s
sys 2m55.548s
After:
time check -qcow2 -j 12
...
real 2m12.136s
user 12m40.948s
sys 4m7.449s
VERY excellent. And this will probably flush a lot more bugs loose, too. (Which I consider a good thing!)
We could look into utilizing it for 'make check', but we'll have to be prepared for a greater risk of race conditions on the CI if we do. But... it's seriously hard to argue with this kind of optimization, very well done!
Hmm, seems -j 6 should be enough. I have 6 cores, 2 threads per core.
Anyway, that's so fast!

iotests/testrunner.py: add doc string for run_test()
iotests/testrunner.py: move updating last_elapsed to run_tests
