This is to pad the payload for variances in what is actually accessible for the payload as a result of using the httpclient mixin and all of the extra HTTP get stuff (i.e. user agent) it adds in. On my system with the headers set, I only need padding of 1 byte to prevent the payload from being cut off, but that may change depending on the specifics of the connection, so padding it a bit just ensures the payload can be found by the egghunter.

Some notes on the egg itself below though.
