def __fork_pty(self):
        '''This implements a substitute for the forkpty system call. This
        should be more portable than the pty.fork() function. Specifically,
        this should work on Solaris.

        Modified 10.06.05 by Geoff Marshall: Implemented __fork_pty() method to
        resolve the issue with Python's pty.fork() not supporting Solaris,
        particularly ssh. Based on patch to posixmodule.c authored by Noah
        Spurrier::
