Thx for that. A need to use both sockets and a serial connection, and my
preferred way would be to use a single select statement so the whole thing
goes into a waitstate. If I use serial and sockets from different libraries
I have to use a loop.

So if cygwin doesn't handle that, then using a loop; what is the common
interval to poll sockets and serial, that works best yet minimizes the cpu
usage (busy-wait)
