It appears to me that the only problem right now is that the DWARF-2
EH table (objects, in frame-dwarf2.c) is currently static.  Couldn't
we just make it global, so that ELF symbol-binding semantics resolves
it to a single symbol globally?  On platforms that don't have ELF
library semantics, we might be able to work around this with an
additional level of indirection and explicit symbol resolution at
initialization time.
