Yep, I can confirm. Undoubtedly the result of a blocked read. I tried
to modify the way SWITCHER handles reads, but there seem to be a dozen
different pathways to read/write on the communications channel, all
making for a god awful mess. Most likely it's blocking in read1().
Unfortunately, handling the blocked read is not straight forward. I'll
try to look at it again, when I can.
