Yeah, I don't like this at all.  I always thought that the flashing console
thingie was truely lame,. and made Insight look really bad. IIRC, the only
reason that we didn't build with -subsystem-windows (sic), and thus
eliminate this particular wart was that in the bad ole days the only way to
run the gdb testsuite on Windows was to telnet in and use expect, and that
required -subsystem-console.  Now that you can run the testsuite on Windows
successfully, there is no good reason for this.

Yeah, I was hoping that you could do something really simple like register a
readable file-event for stderr, and respond to output there, but it looks
like Tcl doesn't open stderr readable, and I have no idea what havoc doing
this would wreak...  OTOH, things like the TkCon extension are able to
redirect all the standard channels into a text widget, all from Tcl.  It
might be a good idea to have a look at what TkCon does, and just copy that
early on in the startup process...
