+1 to Warner's sentiments.

gdb in base doesn't work well with threads (6.x never did ;/..), and lacks support for other things (like python debugging). Being able to debug threads reliably is a make or break thing.

So while I understand and in general agree with you Rod, I completely disagree on the practical end of things. I'm actually kind of curious as to why this isn't being done globally.. but I assume that it was described in one of the many threads some time ago about the status quo for debugging with gdb on tier-two architectures.
