I'm working on a Windows application that grabs GPS and Iperf data. My
app accesses the GPS receiver through a serial port by way of
GPS::NMEA, and it gets the Iperf data by way of `iperf -c $options`.
The backquoted command works until a GPS capture has been performed,
but after even a single GPS capture the backquoted Iperf command, in
fact *any* backquoted command, causes my app to hang. An attempt to
have the command pipe its output to a filehandle gives the same result.
Note: My GPS code closes the serial port after each capture.
