100% agreed, both in the ideal bit, and on the task size bit. :-) For
true/always/full sharing, I'm thinking that we'd have to rework how gdb
addresses symbol values (we relocate everything early; we'd have to apply
relocation offsets on demand), and, we do some sorting of symbols, since
sections may end up loaded at different relative offsets within the
same objfile for different inferiors, in some targets. E.g.,
/* Relocating different sections by different amounts may cause the symbols
to be out of order. */
