When it does this, is it one thread that is using lots of CPU, and
the others are using zero?

Perhaps one thread for each lost connection plus the main thread
area all using CPU?

It could be the waits that we have at the end of the loops.
UpdateTime() runs fairly quickly, but shouldn't be doing much if
there aren't any inputs.

The read threads for each interface may be looping very quickly when
a connection is lost.

If could sort a "top" listing by memory usage, all of the Xastir
threads should be grouped together.  Usually the lowest numbered
process would be the main thread.
