2013-09-30	erts: Refactor the ASSERT macro	Sverker Eriksson
	Introduce unconditional ERTS_ASSERT and use that for both ASSERT and ASSERT_EXPR.
2013-06-19	erts: Add new allocator strategy aoffcbf	Sverker Eriksson
	with better performance than aoffcaobf as we don't have to rearrange the search tree when there are blocks of equal size.
2013-06-04	erts: Carrier pool information in allocator information	Rickard Green
	That is, include information about carrier pool in result returned from erlang:system_info({allocator,allocator_sizes, _}).
2013-06-04	erts: Use carrier pool for migration of carriers	Rickard Green

2013-06-03	erts: Remove unnecessary flag arguments in allocators	Sverker Eriksson
	A cleanup after SBMBC was removed.
2013-06-03	erts: Remove SBMBC allocator	Sverker Eriksson

2013-06-03	erts: Add test for add_mbc and remove_mbc callbacks	Sverker Eriksson

2013-06-03	erts: Fix deallocation in removed carrier	Sverker Eriksson

2013-06-03	erts: Change naive list to rb-tree of carriers in AOFF allocator	Sverker Eriksson
	and add new callbacks add_mbc(), remove_mbc() and largest_fblk_in_mbc() for carrier migration.
2013-06-03	erts: Prepare aoff allocator for carrier migration	Sverker Eriksson
	by putting blocks from different carrier into separate search trees. Carriers are currently organized in a naive linked list by address order.
2013-06-03	erts: Make carrier header sizes customizable	Sverker Eriksson
	This is a modified partial revert of 2ab1d972f6fd37c17b05
2013-06-03	erts: Add "bestfit within carrier" for aoff allocator (aoffcbf)	Sverker Eriksson

2013-05-06	erts: Change some more 'long' to pointer sized int (ErlDrvUInt)	Sverker Eriksson

2013-01-25	Update copyright years	Björn-Egil Dahlberg

2012-11-21	erts: Make carrier header sizes compile time constants	Sverker Eriksson
	No allocator strategy is using customized carrier headers anyway.
2012-11-15	erts: Add carrier pointer to header of free block	Sverker Eriksson

2012-11-15	erts: Add carrier offset to internal allocation headers	Sverker Eriksson

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.
