This does not need a subprocess, and can be done efficiently in python,
like suggested in my review of patch 10.

Note thatif the search pattern does not occur at the beginning of the
line, we can do:

    s = 'blabla'
    for open(log_path, "r") as f:
        lines = [l for l in f.readlines() if s in l]

Ditto for the other test, of course. ;-)

Regards,
Yann E. MORIN.
