Unix select behaviour for pipes could be emulated on Win32 using PeekNamedPipe().

Although the function name suggests that this is design for use with named pipes, it also works with anonymous pipes:

hNamedPipe in

A handle to the pipe. This parameter can be a handle to a named pipe instance, as returned by the CreateNamedPipe or CreateFile function, or it can be a handle to the read end of an anonymous pipe, as returned by the CreatePipe function. The handle must have GENERIC_READ access to the pipe.

Similarly, can_read() could be implemented for files using Alertable IO, and callbacks placed on the Asynchronous Procedure Queue.

Implementing either would require a substantial rewrite of win32_select() in win32sck.c

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.

The start of some sanity?
