	* Use less memory when reading CPU profiles
	* New environment variables to control kernel-allocs (sbrk, memfs, etc)
	* Add MarkThreadBusy(): performance improvement

	* BUGFIX: weaken new/delete/etc in addition to malloc/free/etc
	* BUGFIX: Fix return value of GetAllocatedSize
	* PORTING: Fix mmap-#define problem on some 64-bit systems
	* PORTING: Call ranlib again (some OS X versions need it)
	* PORTING: Fix a leak when building with LLVM
	* PORTING: Remove some unneeded bash-ishs from testing scripts
	* WINDOWS: Support library unloading as well as loading
	* WINDOWS/BUGFIX: Set page to 'xrw' instead of 'rw' when patching
