@ - Greatly improved performance, by switching the signal callback mechanism @ to use ticks @ - Implemented object signal callback ability by using array($obj, $method) @ - Added a restart parameter to pcntl_signal, which allows you to disable @ the default of system call restarting Changed callback hash table to be initialized and destroyed per reqeust (allows the ability to use request life zvals as handles) Nuked warnings Modified test script to adjust to new ticks backend Some slight WS fixes
