Very likely not, in all cases :o(

I'd advise looking at the libevent code to see what they do. There 
should probably be some version of that lisp quote, but for libevent ;o)

TBH it seems crazy-broken that OS X isn't returning pending errors but 
does then return an error on write(). Maybe that's an OS X bug? What 
type of sockets was this with?
