Actually, I don't know of any case where it ends up generating incorrect
byte-code. It will signal different (fewer) warnings and things like
that, but AFAIK the generated byte-code should be pretty much
equivalent. Moreover, if it ever ends up generating incorrect
byte-code, it's most likely because of a bug in some other file
(typically, the bug would be that Emacs's behavior is modified just by
loading that file).

It is significantly faster on uniprocessor machines.
I don't think we should remove it, but we should definitely rename it
because nothing in "compile -vs- recompile" hints at the difference.
We could rename it to "single-process-compile" or something like that.
