      * system() and exec() closes non-standard file descriptors

  * The :close_others option is true by default for system() and exec().
    Also, the close-on-exec flag is set by default for all new file descriptors.
    This means file descriptors doesn't inherit to spawned process unless
    explicitly requested such as system(..., fd=>fd).

  * Kernel#respond_to? against a protected method now returns false
    unless the second argument is true.
