Bug #21509: io/wait: IO#wait raises error when passed nil as timeout

[chucke (Tiago Cardoso)]

The documentation of the method goes:

wait(timeout = nil, mode = :read) → self, true, or false 

However, when passing nil in the first argument, it fails:

io.wait(nil, :read_write) #=> in 'IO#wait': can't convert NilClass into time interval (TypeError)

This seems inconsistent with other variants and related methods:

io.wait(IO::READABLE | IO::WRITABLE, nil) #=> 5
io.to_io.wait_readable(nil) #=> returns the socket
