   While we are talking: someone (H.J. Lu?) suggested to make the
   watchpoint insertion code common to all x86 targets.  What's the
   current say-so on this?

I haven't yet looked into the HW watchpoints yet.  We probably could
use the same logic for choosing the appropriate debug registers, but
the way the registers are accessed wil differ considerably among the
various i386 targets.  When fiddling the code we should keep
multi-arch in mind.
