//
// 2011-05-27 修正 nextTick 造成管線阻塞
// 2011-05-28 runTF 裡,  l_busy設為 true 和 l_nativeRunTF 的執行順序 issue (假如 tf 只有一項, 則會有 l_busy 為 true 卻停止 tick 的情況.
// 2011-05-28 l_nativeRunTF 裡, 函數執行完畢釋放 object issue
// 2011-07-20 更換 fifo queue algorithm (http://code.stephenmorley.org/javascript/queues/)
// 2011-09-04 簡化執行流程
