Yeah, seems that i understood you correctly the first time then. I'm not 
completely convinced that this overhead and complexity is worth the 
trouble, to be honest. I mean, it's not like we're going to sleep 
indefinitely, this isn't like pthread wait - the biggest sleep time i've 
seen was around half a second and i'm not sure there is a use case for 
enabling/disabling this functionality willy nilly ever 5 seconds.
