The creation and disposal of contexts is delegated to an external ContextExecutableInputSUL.ContextHandler
.

If SUL.canFork()
returns true
, this method must return a non-null
object, which should
behave exactly like this SUL (in particular, it must be forkable as well). Otherwise, a UnsupportedOperationException
must be thrown.
Implementation note: if resetting a SUL changes the internal state of this object in a non-trivial way (e.g., incrementing a counter to ensure independent sessions), care must be taken that forks of this SUL manipulate the same internal state.
