GDB can help you with this if you you do ``set stop-on-solib-events 1''.
You'll probably want to do this well after your program has started
though to avoid stopping every time one of the shared libraries specified
on the link line gets loaded.

Have you disabled ``auto-solib-add''?  If not, you shouldn't need to
invoke the ``sharedlibrary'' command directly.  I.e, gdb should
automatically load the shared libraries for you (unless you've told it
not to).

Which platform are you running on?  On most platforms, gdb should
be able to use whatever resources the operating system is able to
give it.  Thus, you may need to play around with ulimit, adjusting
the amount of memory, swap space, etc.
