great.  feel free to drop my patch.  but hopefully people find it useful 
in their own programs until maxim's series is widely available.

i'll keep using them for the time being, since the "spill before 
verifying" was just one of many things i've seen.  that, and it takes me 
a while to get new kernel features in production.  =)

thanks,
