I think a basic non-blocking interface should be similar to the 
synchronous one, but also exposes a file/socket descriptor to 
pass to the event system and also provide status method for 
whether the R/W operation is waiting.

I need to look into this more, but the OCI non-blocking model is 
problematic (a missing file descriptor maybe).  It can probably 
be made to work since Node now has a driver directly from Oracle, 
but I'm not sure if it has the same scaling profile as other 
non-blocking clients.
