+ *	Performs a low-level <methodname>select</methodname> call, which waits for data
+ *      to become available from input/output devices. The first three
+ *      parameters are arrays of +IO+ objects or +nil+. The last is a
+ *      timeout in seconds, which should be an +Integer+ or a +Float+.
+ *      The call waits for data to become available for any of the +IO+
+ *	objects in _read_array_, for buffers to have cleared sufficiently to
+ *      enable writing to any of the devices in _write_array_, or for an error
+ *      to occur on the devices in _error_array_. If one or more of these
+ *	conditions are met, the call returns a three-element array containing
+ *      arrays of the +IO+ objects that were ready.  Otherwise, if there is no
+ *      change in status for _timeout_ seconds, the call returns +nil+. If all
+ *      parameters are +nil+, the current thread sleeps forever.
