No code shown either. And no reason deployed, why we couldn't
code this without trampolines in the old threads.

I've followed these threads and got no answer. I only saw
comments like "it is _really_ needed, because XXX uses it." But
never saw _any_ code, which will perform much worse without them.
I only know, that there exists code, which uses it, but never
been able to understand the reasoning behind doing it that way.
So I still wait for a beating performance argument (factor or
order of magnitude) ;-)
