It's impossible to implement a vt100 emulator using a text widget,
I'll go ahead and warn you. If I were doing this I would make the
xterm sources into a library that could be used in a GTK widget.

The child is sharing an X connection with the parent; won't work at
all. Child should simply reap the grandchild then _exit(). (note
underscore prefix)
