What kind of "thread safe" are deque's actually?

	The entire Python object/data model.

	Data is not "stored in" variables -- rather names are "attached to"
data.

	sorted() creates a new data object, allocating memory for it. THEN the
name "data" is attached to this new data object (and disconnected from the
previous object). If there are no names left connected to the original
object, the garbage collector reaps its memory.
