Well, for instance, if I have a segfault in another thread, gdb
doesn't switch right to it.  Nor can I do it manually (info threads
returns nothing.)  I can attach to the other threads externally by
doing a gdb ./progname pid  but that's a real pain when you have like
4-5 threads and you don't know which one is croaking.

I haven't tried the development version source, but I have tried the
latest cvs version of stable.  I'll try the devel version today.

I'll see if I can come up with some.

Yeah, I posted to the gdb list at the same time I posted here.  Have
only gotten a few responses from (I assume) non-maintainers so far,
and it's been recommendations for other products to use.
Unfortunately, I tried all of those, and they don't do too much
better. ;D
