Render after multiple calls to show seem unintentionally delayed

[SimoneMSR]

When calling the show function after the toast has disappeared, the second/3rd/n-th toast is rendered with some unexpected delay

<Button 
  title="Press Me" 
  onPress={()=>{
      console.log("will present toast " + new Date());  
      this.refs.toast.show(""+new Date(),100) 
   }}>
</Button>

<Toast 
   ref="toast"
  position={'top'}
/>
