Yes, I agree that this is the way to go.  Particularly, once we've read
a symtab in we should never need the corresponding psymtab again.  Of
course, there are more partial symbols than minimal symbols; and
symbols take more memory than partial symbols.  So it's not trivial.

By the way, I noticed something very interesting today.  SGI apparently
had DWARF-2 extensions including a .debug_typenames section (and var,
func, weak names) to expand upon the concept of .debug_pubnames.  We
could make GCC generate those and then use them to build psymtabs, I
bet.  That would speed up load time a lot.

Oh well, something else for the List.
