In the kernel though, there are many codepaths where *every* *single* instruction counts; that could be a serious performance hit.

Write *those* *codepaths* in *C* or *assembly*. But only after you manage to measure a difference compared to the object-oriented systems language.

[I really doubt there are that many of these; syscall entry/dispatch/exit, interrupt dispatch, context switch, what else?]
