The code I mentioned can now be found at http://wiki.tcl.tk/28182.

Useful reading is also http://abel.math.umu.se/~lars/tcl/hubs.pdf, but 
bear in mind that the scope of the problem that it set out to address is 
somewhat larger than just controlling a child tclsh, so there are a lot of 
issues considered that you're probably not so interested in.

For a first experiment, you might want to try something like the following:

% hubs::interp::local_spawn my -prog tclsh8.4 -shake 1
Hello, I'm nova.local 19741 /usr/bin/tclsh8.4 8.4.19
::my::slave
% ::my::slave eval {array get tcl_platform}
osVersion 10.6.0 byteOrder littleEndian tip,268 1 threaded 1 machine i386 
platform unix os Darwin tip,280 1 user lars wordSize 4
% exec ps -p 19741
   PID   TT  STAT      TIME COMMAND
19741   ??  S      0:00.10 tclsh8.4
% ::my::slave exit
% exec ps -p 19741
Error:   PID   TT  STAT      TIME COMMAND
child process exited abnormally
%

(ps exits with a nonzero status, since the process 19741 wasn't around 
anymore.)
