<font face="Helvetica, Arial, sans-serif">I am looking at the
implementation of POpen and PClose in the runtime-library for
Darwin (or more general for UNIX). It seems like it doesn't call
into libc popen and pclose, but instead follows its own
implementation in unix.pp in POpen_internal. I am just curious to
know the reason.<br>
