2012-07-31	Improve the enqueue operation of delayed dealloc	Rickard Green
	The enqueue operation have been re-written to behave better during heavy contention by spreading writes over multiple locations. This enqueue operation also take advantage of the delayed aux work wake up functionality and can by this omit one memory barrier.
2011-11-13	Optimize memory allocation	Rickard Green
	A number of memory allocation optimizations have been implemented. Most optimizations reduce contention caused by synchronization between threads during allocation and deallocation of memory. Most notably: * Synchronization of memory management in scheduler specific allocator instances has been rewritten to use lock-free synchronization. * Synchronization of memory management in scheduler specific pre-allocators has been rewritten to use lock-free synchronization. * The 'mseg_alloc' memory segment allocator now use scheduler specific instances instead of one instance. Apart from reducing contention this also ensures that memory allocators always create memory segments on the local NUMA node on a NUMA system.
