Running hostapd in the foreground with debugging generates multiple
copies of the following block:

There was one recorded device timeout overnight.

As an asside, what syslog facillity/level does hostapd use?  I was unable
to get hostapd to use syslog and am probably not logging the right
messages in my syslog.conf.
