Please don't overload the x86 buildsys

Hi! Just a note: The network connection to the x86 builder is not the fattest afaics. So if more then one big package is build and still downloading then it seems to happen that other big packages build directly after that will fail to download with a error message like this: Requeuing the job should just get the package built. So if you know you package is big or if you know other big packages are in the queue then please wait a bit before queuing more jobs. Yeah, that sucks, but we have to live with that (¹). I'm working on installing a second x86 builder; hopefully that will make this problem show up less.
