That could be. I'll have to take a look at it.

Yes, it suffers from this problem still. (Mutter something about how I'd
thought I'd fixed that at least a dozen times already.)

What we really need is a better way to destroy these things. Hopefully,
that infrastructure is not far off... I'm just waiting for someone in gdb
to clean up ONE little thing, and then we can fix this once and for all,
whack a whole bunch of globals from the source window, delete a bunch of
source window code, and introduce ui-out into gdbtk. I've had a uiout
builder for insight for months now, but we cannot use it yet. :-(
