That is not a good idea. The overall behaviour of entering the
debugger in inherently MI. The MD specifics are in the details,
which require nothing more than some MD callback functions to
fill in the blanks or create the right abstraction.
Race conditions are not MD phenomena either, but may require MD
techniques to prevent them. Hence, to fix race conditions you
don't have to degenerate MI code to MD code, provided you have
proper MD callback functions to fill in the blanks or create
the right abstractions.
