Didn't the L4 folks find a way to make system calls on Pentiums without using

The nice thing about the way Matt's designing the API is that you can change the mechanism for the system call and you only need to change the messageport send routines. So this kind of thing is more an implementation detail than a basic design decision.

Sure... that's why I brought it up.... Matt's design seems to shield us from the
backend which could use any optimal/reliable path.
