// eg.
var Pool = require("fib-pool")
var co = require("coroutine")

var p = Pool(() => {
throw new Error("Test create error");
});

co.parallel(() => {
try{
p((pooled) => {
console.log("tx operation: pooled value = %s", pooled);
});
}catch(e){
console.log("Can't get pooled object - %s", e)
}

}, 11); // 大于10时会永远阻塞！

console.log("quit");
