A TSem is an unusual sort of lock in that it only protects the same thread from acquiring it twice. Different threads may acquire the same TSem without problems.

The purpose of this is to allow computations which potentially would loop forever by calling themselves to instead fail gracefully. To aid in this process, we also include in each TSem a String. When we attempt to acquire a TSem which is already acquired, we instead return the String for this TSem and the TSems acquired within this one.
