I'm no authority on this (and you're really better off asking on the gdb
mailing list, where the real experts are hiding), but I'll mention what
I've done...

I wait for the shared library to be loaded, then set a break in it.
This, of course, means that you'll have to wait for the dlopen to
complete. This isn't usually quite so difficult as it is annoying.

However, as I recall, there should be some new gdb feature, pending
breakpoints. In GDB 6.1:
http://sources.redhat.com/gdb/current/onlinedocs/gdb_6.html#IDX151

You should be able to use this, but you'll have to set it in the
console, since Insight itself does not yet understand these.
