Are you referring to SMP here?  Where else is it deficient?

Is this because of its design or implementation?  If design, what tradeoffs do
the faster microkernels make?  Speed is IMHO less important than simplicity
of design, maintainability of the code base, and stability.  How does
gnumach fare in these categories?  When you mentioned that it's aging, were
you also implying cruft and bitrot?
