   Has anyone looked at this, or got any suggestions/comments?

AFAICT setting breakpoints in preloaded libraries seems to work fine
on i586-pc-linux-gnu with a glibc-2.1.3 snapshot.  Setting breakpoints
works and they are properly triggered.

Arthur, can you provide a small test-case, that shows your problems?
