No, but being a genius sure helps you beat the odds.

Well, actually he was writing about GCC....

You're missing Linus's point, I think.  Linus did *not* claim that
it's impossible to write a fast *GC*.  He claimed that it's hard to
write a fast *program* that uses GC for memory management.  A
benchmark that stresses *only* the memory management system is
unlikely to impress him.
