I think John's point is that if Hurd used a RT-enabled version of Mach,
he could run his RT processes at a low level in parallel to the normal
Hurd stack, which would provide any necessary higher-level
functionality. That would be pretty much the same as DROPS does with L4
and L4Linux. IMHO a rather interesting area for Hurd development --
though I guess we can't do much more than providing guidance in this
case...
