+ - Changed: exception handling. Now, exceptions raise by invoking new
+ cds::throw_exception() function. If you compile your code with exception disabled,
+ the function prints an exception message to stdout and calls abort()
+ instead of throwing.
+ - Flat Combining: fixed memory-order bug that can lead to crash on weak ordered
+ architecture like PowerPC or ARM
+ - Added: erase_at( iterator ) function to MichaelHashSet/Map and SplitListSet/Map
+ based on IterableList
+ - Fixed a bug in BronsonAVLTreeMap::extract_min()/extract_max()/clear().
+ - Removed: signal-handled threaded uRCU (cds::urcu::signal_threaded) due
+ bad performance
