Objects may be GCed when they are no longer 'live'. An object is considered to 
be live if it is:
a) On the stack
b) In the registry
c) In the globals table
d) Referenced by a /Lua/ object that is live (excepting weak tables).

Just because a thread has not terminated does not make it live, so to ensure 
that it is not GCed you need to put a reference to it in one of the above 
places; probably the registry.
