Currently, the documentation for select says

WARNING: One should not attempt to mix buffered I/O (like read or <FH>) with select, except as permitted by POSIX, and even then only on POSIX systems. You have to use sysread instead.

This should be present in the documentation for IO::Select as well.

(I wonder what exceptions POSIX makes, and if they are still applicable to Perl.)
