Use lazy I/O to consume all elements from a Source.
This function relies on monadActive to determine if the underlying monadic state has been closed.

Use lazy I/O for consuming the contents of a source. Warning: All normal
warnings of lazy I/O apply. In particular, if you are using this with a
ResourceT transformer, you must force the list to be evaluated before
exiting the ResourceT.

Determine if some monad is still active. This is intended to prevent usage
of a monadic state after it has been closed. This is necessary for such
cases as lazy I/O, where an unevaluated thunk may still refer to a
closed ResourceT.
