Thanks for the patch.  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?

Thanks,

Michael
