* io.c (rb_io_close_read): keep fptr in write_io to be discarded, to
fix freed pointer access when it is in use by other threads, and get
rid of potential memory/fd leak.
* io.c (rb_io_close_write): detach tied IO for writing before closing
to get rid of race condition. [ruby-list:49598]
* io.c (rb_io_close_read): duplex IO should wait its child process
even after close_read.
