Hi Chris,
Thanks for the response.  So then how does one get any kind of
notification if the context goes away?  Is this something the user
making the patch would have to take care of?  For example, let's say I
had a shader in a Lua script.  When the context the shader is compiled
and allocated in goes away, I'd like to be able to free its resources
just before it is deallocated.  Is there a way to do this?

thanks,
wes
