I think that this should be converted to a future, which can be derefed directly and is run within a thread implicitly. However, I didn't want to make a potentially breaking change without checking with you first, @aroemers.

Combining the approaches of using the InheritableThreadLocal and a binding so we can fall back to the *session* if the InheritableThreadLocal's value is missing.
