- Scheduler is either initialized at server start or never. Starting & stopping is now suspending & resuming. - The scheduler has clear OO interface - Now all calls to the scheduler are synchronous - GLOBAL event_scheduler uses thd::sys_var_tmp (see set_var.cc) - External API is encapsulated into class Events - Includes fixes for all comments of Kostja's review of 19.05.2005 Starting to merge into 5.1-release (5.1.10) and push
