Saw (via cable) a talk at Stanford by one of the 80860 people from Intel where he said (I believe) that the chip provided the ability to do just that. Upon examining the Programmer's Reference Manual, I find that up to 32 user-mode instructions can be protected by a LOCK instruction (no branching allowed, must be restartable from the LOCK in case of traps). That sounds like what you want. David
