Nope. I dug into this a bit and after a git bisect -- thanks once again
to IBM for gcc111, quite a nice machine -- I'm sorry to report that the
AIX solib rewrite seems to have broken thread debugging there.
0c4f667cfe5118bf3a2690502a9a40ff3309abed works:

I couldn't try 4d1eb6b4d299f3e46aab18e08fe4ef3063a39565 because I didn't
build with the expat support (and this revision introduced a build
failure in this scenario), but 814a3ff71b0e90f67eb9003ca37fa90094204152
(which fixed the build problem) does this for the same program, stopped
at the same spot:

CCing Joel.
