How are you benchmarking this?

The changes concerned in my email are all of the form -

#define GSI_MAP_KEY_RETAIN(A)           [A retain]

becomes -

#define GSI_MAP_KEY_RETAIN(M, A)                [A retain]

ie. there is an extra argument to the macro, but that argument is not 
used,
so the generated code should be identical (which is why the compatibility
issue should only arise when compiling, not with binaries).


If it's previous changes ... the main thing is a switch from using 
select()
to using poll() in NSRunLoop, and a load of changes to the internals of 
NSRunLoop
which should have speeded it up (though that was not the reason for 
making them).
Unfortunately I don't have any NSRunLoop benchmarks though, so I'd be 
really
interested in your benchmarks.
