* eval.c (block_pass): allow "retry" from within argument passed

Browse source 
block. [new]

* eval.c (localjump_error): should preserve exit status in the
  exception object. [new]

* eval.c (proc_invoke): should raise exception for "break" if it's
  yielding, not calling. [new]

* eval.c (block_pass): should NOT raise exception for "break". [new]

* eval.c (block_pass): should allow block argument relay even in
  the tainted mode.

* ext/socket/socket.c: support subclassing by proper "initialize"
  calling convention. [new]
