Assuming a remote target, I can see that this would work in situations
where you have access to the hardware breakpoint registers via the
remote protocol. However, in situations where the ``native watchpoint''
mechanism consists of funky ptrace() calls (or the like), this clearly
won't work. (E.g, I don't think this could be made to work for
Linux/IA-64.)
