   I agree completely-- keeping a "thin" stub is definitely the way to go.

Absolutely, if it's possible.

   In retrospect, what I'm after may be something less related to what you
   guys are talking about than I thought...  If I'm trying to make gdb
   "aware" of an RTOS like uC/OS or eCos, for which I have sources, then the
   kernel data structures should exist as symbols, so I should be able to
   peek/poke at them with regular gdb functionality when the target stops.

Sources are convenient, although of course they're not available for
many OSes that we want to support.  Also, you could run into a situation
where the OS sources changed slightly, so symbol-based scripts fail,
while a protocol-based design would continue to work.
