Koichi Sasada caac5f777a make monitor.so for performance. (#2576) ... Recent monitor.rb has performance problem because of interrupt handlers. 'Monitor#synchronize' is frequently used primitive so the performance of this method is important. This patch rewrite 'monitor.rb' with 'monitor.so' (C-extension) and make it faster. See [Feature #16255] for details. Monitor class objects are normal object which include MonitorMixin. This patch introduce a Monitor class which is implemented on C and MonitorMixin uses Monitor object as re-entrant (recursive) Mutex. This technique improve performance because we don't need to care atomicity and we don't need accesses to instance variables any more on Monitor class.		2019-10-20 04:52:20 +09:00
