possible reason:
In case of collision CacheVC::removeEvent() called do_read_call(). Handler of
cache vc was set to handleReadDone() by handleRead(). If handleRead() also
returned EVENT_RETURN, CacheVC:removeEvent() jumped to label Lread. If
collision was detected again, do_read_call() may be called once more. In this
situation, handleReadDone was saved in save_handler. At the end of
handleReadDone, POP_HANDLER finally led to infinite loop since save_handler
pointed to handleReadDone.
