I thought you were already  allowing strings as subscripts?

(as in the example a["foo"] += "bar" )

Porbably you shoudl treat the thread ID as opaque and only use it in ways 
that rely on two IDs either comparing equal or not. If you hash it in some 
way and used that hashed value, then you're going to end up with obscure 
bugs caused by collisions.
