Hi Michael, if the server is missing in action, one may want to retry at regular intervals (via sleep and goto) but until a download starts making progress, all that polling is a bit overkill, since we'd be just receiving a few seldom packets.

At what point does this help with CPU utilisation? iPXE will currently use 100% CPU while network operations are in progress, and should sit mostly idle while waiting for user input (e.g. at the command line). I'm not understanding the circumstances in which your patch helps. Could you explain?
