185 can sometimes produce wrong output like this:

Failures: 185
Failed 1 of 1 tests
=========================================
This is because quite happens before first mirror request is done
(and, in specified case, even before block-job len field is set).
To prevent it let's just add a sleep for 0.3 seconds before quite.

v2: just add a sleep instead of filtering output (proposed by Kevin)
