Maybe I was particularly unlucky  in my setup (NFS and stuff), but last time
I tried the difference was more than a factor of 2.

Sure.  But it's the author's responsibility to watch for those problems and
he most likely compiles from within his running Emacs anyway, so the
difference doesn't even appear in the picture.

I think it is.  Using `fboundp' to see if a function will be available when
the code will be run is OK for a quick-and-dirty solution, but it's
otherwise just naive.
