+- Fixed a bug in socket_select() that could cause unexpected behavior when
+  using a statement like $w = $e = array($sock); This change unfortunately
+  prevents the use of constant values (e.g. NULL) for the socket array
+  paramaters. Instead, use a temporary variable or an expression with the
+  leftmost member being a temporary variable. ex.:
+  socket_select($w, $r, $e = NULL, 10); (Jason)
