Sorry, I'm lost here.

Say, instead of a libthread_db, we had gdb/libthread-db.c which could be 
compiled on all systems.  It would have some sort of procedural 
interface, and would grub around in target data to find thread X lwp 
maps.  However, it could be written in a way that was host architecture 
netural.
