Brltty does things like use non-blocking I/O and subject each I/O operation to
a timeout, so it's hard to see where it might be getting stuck. Also, if this
were a general problem then I'd expect that we'd be getting a lot more reports
of it.

These things being said, it's always possible that there's something about your
particular environment which is being a catalyst. Could you keep a running
debug log so that we'll have something to look at the next time it happens?
