i found the bug here. in limiter we should return the b3.RUNNING instead of b3.SUCCESS or b3.FAILURE
cause the b3.SUCCESS or b3.FAILURE would exit the running state and reset the time in open when we tick again

[linhaiwei123]

yep i found that return b3.RUNNING in limiter still not work well. the only way to fix it is to check whether the key i is set or not. and set it in the first time we enter the open callback

@linhaiwei123 would you be able to submit a PR with the failing test or a simple way to reproduce the bug?

open: function(tick) {
tick.blackboard.set('i', 0, tick.tree.id, this.id);
},
The Decorator of Limiter will reset "i" to zero when child status == b3.SUCCESS || status == b3.FAILURE。 +1 ，reset 0， +1 ，reset 0……
