Keith's analysis of the situation is correct.  expect uses a unix-like
version of tcl and insight uses a windows version of tcl with hooks for
cygwin.

Using the cygwin version of tcl for expect allows expect to use select,
ptys, and other unix-isms.  Using the windows version for insight allows
insight to draw windows on the screen.

This is a fact of life.  It isn't going to change no matter what mailing
list you discuss it in.
