It doesn't happen in any performance critical path that I've seen.
Sure it does, watch with strace what running a fairly involved GNU configure script does. It also happens to be one of the best tests for getting all the tlb and cache flushing correct during fork and exit as well.
If you do fork and exit stupidly from a architecture specific MM layer perspective, fork+exec("anything") will look even more stupid. To me doing the former correctly goes hand in hand with doing the latter correctly. Any time I've improved fork/exit numbers, the exec tests showed improvements as well.
