retargeting PR#26 for mozsvc dev
Add timeouts for router
Fix for ContentLength logic
Convert to ticker

Convert bucketSend to use channels

  failed or slow server responses anyway.
* moved client gen to New to prevent unneeded duplications
Add buffer 1 to router send

* also added longer timeout to avoid possible races.
