	This scenario as you describe it is not possible (task 2 allocates
nothing, therefore frees nothing when RemTask()ed).  In order for Intuition
to Signal() you, you *must* allocate a signal bit (AllocSignal()).
Consequently, you must free it before your task exits.

	Since you're doomed to allocating at least the signal, you may as
well open the whole window....
