[Swift-devel] scheduler foo

[Ben Clifford]

Some subset of the below  patch changes the behaviour to more what I 
would expect - more functional but less optimised.

It suggests something is awry with comparing an explicit from-fresh 
overload count with the ongoing cached value.

I hope you like output on stderr ;)

I'll poke with this a bit more later but I have to work on other stuff 
right now - the patch looks horrible but you might be interested 
in seeing where I go tot.
