What exactly is it that CLORB needs? Does it call unix-select
directly? A pointer to CLORB source where the dependency occurs would
be appreciated.

Please post your test-case. (So we can agree that it tests the right
thing, and hopefully so that someone can use it to drive the Win32
work needed.)

Correct.

Providing supported a select() interface for Win32 as well as *nix
platforms is certainly possible, but it is not going to be
UNIX-SELECT. (Maybe SB-SYS:FD-STREAM-SELECT?)

Tangentially related: energetic Windows hackers wanting to make
FD-STREAMs use HANDLEs on Windows instead of fds would still be much
appreciated. Actually, make that energetic Windows hackers in general.
