Yeah, I seem to remember you've already mentioned it once.

I can see the 2.11BSD source code still has the 32-char interpreter
name limit, yet not the "#! /" magic number handling mentioned there,
i. e. they truly parsed the #! sign.  Not that I'd expect avr-libc to
be compilable on a PDP-11 hosted 2.11BSD though. :-))  (I doubt it
would even compile Perl...)

Maybe, yes.  I could try compiling in a memory filesystem, and see
whether that would speed up things (which it should if we were IO
bound).
