[Spice-devel] leaking drawables

Try the attached patch.  I'm pretty sure qxl just overruns the release 
ring, making complete release lists disappear now and then.

Surprisingly the bits are quite old.  /me wonders how this bug managed 
to stay in the code base unnoticed *that* long.  Any chance older guest 
driver versions used to be more aggressive in emptying the release ring?

cheers,
   Gerd
