LOL, this was also my first idea when I started thinking about porting 
my app to linux. Subsequently it prooved absolutely unnecessary. 
Moreover, I found that epoll-based implementation is much safer than 
winapi-based implementation regarding both programmer's mistakes and 
corner-cases at runtime. Definitely, epoll inventors were pretty smart 
in this respect, imho.
