} }It's only necessary if an optimized SMP-aware kernel can't run on a 386 }(due to use pentium-specific instructions) *and* a kernel that runs on }a 386 is too slow to be usable on an SMP box (due to lack of fast }pentium-specific instructions). Well, "too" is a very interesting word.) Given the amount of tracing code BSD/OS has been able to leave in with trivial penalty I suspect that it won't be "too" slow.
