Applies the fix unit 9 named. Twice a probe printed "armed", carried on and
wrote no draw log -- once because the window lookup failed, once with the
window found and the key sent. Sending the keystroke is not evidence the
logger responded.
After arming, the probe now polls for xenia_re_ui_draws_*.log to exist and
be non-empty, for up to 20 s, and aborts loudly if it does not appear. A
probe that cannot confirm its own instrument is recording is a probe whose
negatives mean nothing.
Narrower fixes were tried and were not enough: making the window lookup
fatal caught the first failure and not the second.
