2011-12-02	Fix time types	Rickard Green

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.
2011-06-14	Use new atomic API in runtime system	Rickard Green
	All uses of the old deprecated atomic API in the runtime system have been replaced with the use of the new atomic API. In a lot of places this change imply a relaxation of memory barriers used.

	Increases the speed of the timer-wheel
2010-12-15	Use new atomic types in emulator	Rickard Green

2010-09-10	Use mutex instead of rwlock	Rickard Green
	Use mutex instead of rwlock since the read lock is more or less unused and it can be quite contended.
