Oh, I see.  I assumed that the debug registers are per VM; I should
have known better.

In that case, adding the debug registers to the register cache is
probably the way to go (since the other registers are per thread,
right?).  And the functions which manipulate the debug registers
should accept an array of registers as their argument--this should
allow any specific target to DTRT easily.

Does this sound as a good plan?

Threading is possible with DJGPP, but the DJGPP port of GDB doesn't
have any special support for debugging such programs.
