Find another method to create a thread sleep

[adamheinmiller]

Tested a method using HTTP GET timeouts, but that provides a hard 10-second sleep and is too long of a delay. I wasn't able to find a way to change the timeout.

Does this help? http://mrhaki.blogspot.com/2011/09/groovy-goodness-use-connection.html

i stumbled over that and also recent issues with poll() in smartthings itself.

The solution I came up with is actually pretty close in timing things correctly :

def sleepForDuration(duration, callback = {})
{
// I'm sorry!

def dTotalSleep = 0
def dStart = new Date().getTime()

while (dTotalSleep <= duration)
{            
    try { httpGet("http://deelay.me/$duration/http://www.google.com ") { } } catch (e) { }

    dTotalSleep = (new Date().getTime() - dStart)
}

log.debug "Slept ${dTotalSleep}ms"

callback(dTotalSleep)

}

the deelay.me is a page that allows to simulate how bad latency can be and basically waits to load the page until the $duration has expired and then invokes the next URL passed (google.com) the cool thing about it is that google.com is rather fast from anywhere in the world thanks to global loadbalancing which means timings are pretty solid.

I made another few changes too i can probably create a PR for it, it's now working reliably and more importantly TIMELY! :)
