I guess I don't see how this is any different from the per-process
ptrace flag on UN*X. Why is this any more of a kludge?

Hmm, yeah, I guess. It's fair to say that noone would expect to be able to have multiple debuggers setting breakpoints and single-stepping on the same entity simultaneously, so having a per-domain mode, or having a notifier chain for debug events, is I guess okay.

But please kill the changes to the domain builders, and change the flag to something like DOMF_debug_mode (I hope to expunge the name 'domu_debug' :-) ).
