Example

package main

import (
    "crypto/rand"
    "github.com/grooveshark/golib/agg"
    "time"
)

func main() {
    agg.CreateInterrupt(1)

    // Create 20 goroutines, each repeatedly measuring how long it takes to run
    // readRand() and aggregating that data
    for i := 0; i < 20; i++ {
        go func() {
            for {
                start := time.Now()
                readRand()
                agg.Agg("readRand", time.Since(start).Seconds())
            }
        }()
    }

    select {}
}

// Reads some random data, we're testing how fast this actually takes
func readRand() {
    b := make([]byte, 16)
    rand.Read(b)
}
