This simple patch makes the DHCP/BOOTP/RARP code sleep with
schedule_timeout() instead of hogging the cpu with cpu_relax() in a
loop. This comes handy when a guest kernel is booted inside QEMU.
Without the patch, the host operating system will consume cpu time
busy waiting.

There are two similar loops involving CONF_PRE_OPEN and CONF_POST_OPEN,
you may wish to hit those while you're at it.

Huh? You mean _removing_ the timeouts involving CONF_PRE/POST_OPEN? I
thought my patch converted all busy waits into schedule_timeout()...
What am I missing?

No, not removing them, but transforming them likewise into
schedule_timeout() calls.

Yeah, but isn't the patch already doing that? I tried to find more
occurances of CONF_PRE/POST_OPEN in the
linux-2.6.10-rc2-mm3/net/ipv4/ipconfig.c but I think the patch covers
all of them. Please point out what I am missing, maybe it is getting
too late for me know...
