Wow, fantastic!  Thanks for this very thorough testing!

I know this happens on some versions of GCC, and I guess it's especially
noticable on a slow VM.  But if you wait long enough, it will eventually
finish.  I think it has some trouble with the (foo 1 2 3 4 ... 2048) call
which we generate through a macro and translates directly to the C
code  foo(1, 2, 3, 4, ... 2048);  :)

I agree, it's not too bad.

Cheers,
