[besich]

In luv example, the every example invoke uv.loop_close() in the end, and the lua engine is core dump.
the loop_close is release some resource, and the loop_gc is also release.
and dont invoke uv.loop_close, the example is good.

Are this bug exists now?

Same thing to #244. Have to be aware of is loop_close must be end of luv apis. If you call loop_close(), you should never call luv api anymore. And in usually loop_close should not be call, because loop object will automate gc by lua.
