What would _really_ be nice would be a way to pass the kind from the sniffer (which really just calls PC_IN_SIGTRAMP) to the frame creation code... not have to read inferior memory to figure out which it is, twice.
I'll think about that, I may need to change the unwinder object anyway.
Just remember that it is the number of unique addresses accessed (0 vs 1 vs 2 ...) and not the number of times each address is accessed that is going to be important - multiple accesses to a single address can be handled with a cache.
