Waits until input is available on some of the given handles.
If no input is available within the given milliseconds, it returns `-1`,
otherwise it returns the index of the corresponding handle
with the available data.
@param handles - a list of handles for input streams
@param timeout - milliseconds to wait for input (< 0 : no time out)
@return `-1` if no input is available within the time out, otherwise `i`
if `(handles!!i)` has data available
