> OpenSSLSocket is currently using the zero byte read trick on Windows to poll 
> for read readiness when peaking at the data to determine whether the incoming 
> connection is performing an SSL handshake. However, io::read is designed to 
> provide consistent semantics for a zero byte read across posix and windows, 
> which is to return immediately.
> To fix this, we can either:
> (1) Have different semantics for zero byte io::read on posix / windows, where 
> we just let it fall through to the system calls. This might be confusing for 
> users, but it's unlikely that a caller would perform a zero byte read in 
> typical code so the confusion is probably avoided.
> (2) Implement io::poll for reads on windows. This would make the caller code 
> consistent and is probably less confusing to users.
