logging is pretty easy to deal with so I created a PR.

bufferedio.c is a little more work as we either need to use the posixmodule.c os.register_at_fork API or expose it as an internal C API to be able to call it to add acquires and releases around the buffer's self->lock member when non-NULL.  either way, that needs to be written safely so that it doesn't crash if fork happens after a buffered io struct is freed.  (unregister at fork handlers when freeing it? messy)
