I've done a similar comparison with the gdb testsuite on native
i686-pc-linux-gnu, (red hat 8.0, LANG=en_US.UTF-8), and the results
came out the same.  I've been using the released versions of
tcl+expect+dejagnu for 2.5 years now.

That's just gdb experience though.

I'm okay with shooting first and fixing problems later.
