-    The test below fails on different systems.  Infact, different
-    systems can generate different "anchors" values for their
-    denoms, therefore the fixed value required by the test below
-    (45) is condemned to fail.
-
-    However, this seems to happen only when very big values are
-    used for the "lookahead_sign" value.  Here we use 3500 seconds,
-    and the test breaks.
-
-    A reasonable fix is to allow for some slack in the number of
-    the expected keys.
