  ARGH....seriosuly?  *sneaks a side look at 1200+ line script in question*.

  Oh dear.  Allow me some time to grieve.

  Ok, over it...  So, it should be fine if I keep all the gui stuff in one
thread...and all the other stuff in other threadS?  I will need more than
two...and here I was thinking I was finished.
  Perhaps the lockups aren't random, but where GUI calls are made to
tcl...hmmm there may be a pattern.  There is a pattern!  Brilliant, now if I
just grow an extra day, I can get this finished on time.
  Argh...perhaps two days...why doesn't tcl just work with threads?  :(
