Right.  I have to allocate my time between 'do stuff with tangible
gdb benefits' and 'do stuff that improves my own infrastructure'.
Sometimes I feel like I'm just infrastructuring my test bed too much.

That is a provocative idea.  I know Jim B wrote one symbol table test
that jumped through a bunch of hoops with the C source code in order
to populate the symbol table in a way that tickled a lookup bug.

On the gloomy side, the test suite can already spot problems faster than
I can file bug reports, and the bug reports are piling up faster than
people can fix them.
