Would it be possible to add some functions to allow a thread to install or
remove a context? Then a thread would still have its own *binding*
to a context, but the flexibility would be there to unbind the context
object and use it in another thread. A function would be able set up a
temporary context and then restore the old one before returning,
making contexts appear to be dynamically scoped.
