Isn't std::streambuf better? Then we could utilize some obscure methods like 
std::streambuf::in_avail() etc.

In my opinion, it's completely independent issue. Event polling is not
nesessarily belong to I/O - for example, in Win32 you can poll whole bunch of
very different events, and not all of them are I/O. May be as first iteration
it would be enough to provide some functionality like "ready/not ready"?

By providing polling class - in Win32 it maps to native call like WaitEvent*,
in unices - poll(2) or select(2). Let me to repeat, I think it is different
functionality, not about I/O.
