Ed Schouten 39154992db Make the RTC checking for QEMU even more aggressive. 
At work, where we use use KVM+QEMU, we notice that pxeboot is pratically
impossible because of network timeouts. This is due to the fact that the
RTC code makes aggressive jumps.

Two RTC reads does not seem to be sufficient. Change the code to check
for 8 identical RTC values.
