You might want to check the 'fdopen' routine on your system to make sure that
they provide a buffer.  Some systems don't create a buffer when the 'fdopen'
routine is called.  This created Mega-problems for me when I tried to port it
to HCX-UX 3.0.  I finally just called 'setbuf' on a 'malloc'ed buffer after
EVERY 'fdopen' routine call, just to make sure.
