-class DelayDelete:
-    """
-    The DelayDelete class is a special class whose sole purpose is
-    management of the DistributedObject.delayDelete() counter.
-
-    Normally, a DistributedObject has a delayDelete count of 0.  When
-    we need to bracket a region of code that cannot tolerate a
-    DistributedObject being deleted, we call do.delayDelete(1) to
-    increment the delayDelete count by 1.  While the count is nonzero,
-    the object will not be deleted.  Outside of our critical code, we
-    call do.delayDelete(0) to decrement the delayDelete count and
-    allow the object to be deleted once again.
-
-    Explicit management of this counter is tedious and risky.  This
-    class implicitly manages the counter by incrementing the count in
-    the constructor, and decrementing it in the destructor.  This
-    guarantees that every increment is matched up by a corresponding
-    decrement.
-
-    Thus, to temporarily protect a DistributedObject from deletion,
-    simply create a DelayDelete object.  While the DelayDelete object
-    exists, the DistributedObject will not be deleted; when the
-    DelayDelete object ceases to exist, it may be deleted.
