Usage: $self
Autosens loop. Checks (once) how long it's been since autosens has run, checks
for various trouble conditions (high load, high CPU temperature), and if it's
been 30 minutes since autosens has run and everything is okay, runs
oref0-detect-sensitivity. Working directory should be myopenaps.
