  New Revision: 58437

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=58437

  Log:
    test/socket/test_basicsocket: handle :wait_readable on read_nonblock
    
    On some systems with slower local sockets, :wait_readable may
    happen and we should wait on it to drain the socket.
    This is a possible fix for https://bugs.ruby-lang.org/issues/13491
    
    * test/socket/test_basicsocket.rb (test_read_write_nonblock):
      handle :wait_readable on read_nonblock

  Modified files:
    trunk/test/socket/test_basicsocket.rb
