This is what I intend to commit (since this isn't only useful in the
initramfs this way we also have it in the acutal root fs) - just in case
you feel like testing a bit more (otherwise I'll git it a whirl
tomorrow):

This helps slow devices when either /etc/init.d/multipath-tools-boot or
the initramfs script are being run although the devices are not ready
yet. 

Thanks: Janusz Dziemidowicz for his suggestions and testing
