I plan to start with a Mac implementation, because that's what I use 
most of the time, but I have a Windows box too and can install Linux on 
virtual machine, if that will be needed.

Yes, I had an idea to implement reactor and proactor the way, user may 
swap implementations, e.g. portable reactor based on select and 
platform specific one using efficient implementation for that platform.

This approach is used in Twisted python web-server (It's licence states 
that it needs attribution only on reuse of descent amounts of code, so 
it might be a good idea to peek for some platform specific details).

Windows overlapped I/O allows to implement proactor on top of it 
without any additional layers, but reactor can be implemented on of 
overlapped I/O too.
