C++ collection classes would be very effective here. And sure, the same 
things could be constructed manually in C, but then you're using piles 
of macro trickery a la vec.h and you lose all your typechecking etc, or 
if you use function dispatching to iterate, you blow your optimization 
opportunities in code that is known to be time-critical. Good use of C++ 
machinery effectively moves functionality out of the GDB source tree and 
lets the compiler do the work instead.
