Using template specialization would change a lot of the pointer types, especially when OS(DARWIN) is true.  This would require a bit more surgery on this cpp file.  Would it be worth restructuring the whole file just to save 6k of memory in a global variable with one instance?

Since this would add a maximum of 64 bytes per TCMalloc_Central_FreeListPadded and there is only an array of kNumClasses of these objects, and kNumClasses is 68, this would use a maximum of 4420 bytes.  I don't think this is anything to worry about.
