* Usage:
*
* ext_open runs the external program and opens a stream for sending data to
* the program.
*
* Once all data is sent, ext_read closes the stream, waits for the process
* to terminate, opens the stream for reading the output generated by the
* external program, and returns the exit status. (Or -1 if the process did
* not exit normally.)
*
* ext_close can be called before or after ext_read to close the stream.
