x11: Make sure stream stays alive long enough

Browse Source 
When unreffing the stream from a different thread, the close function
will schedule its cleanup asynchornously in the main thread.
We need to make sure the stream object stays alive for as long as
that hasn't happened, so ref() it.

Fixes #2003
