That's true. However, note that by default, caching is not enabled
for remote unwinding (which is what gdb does). To enable caching, gdb
would have to make a call of the form:
unw_set_caching_policy(ADDR_SPACE, UNW_CACHE_GLOBAL);
Also, whenever something changes in the target that could invalidate
cached unwind info, gdb would have to call:
unw_flush_cache(ADDR_SPACE, LO, HI);
where LO and HI is the address range that was affected (or LO=0, HI=0
to flush the entire cache).
