+# CVLEN is just the *estimated* never to be exceeded amount of storage needed

+# changing cv_move to count elements instead of moving them.  Then the known
+# counts would be used with amovs to hustle the elements into the "salloc'ed"
+# space.  Instead, with a static count, we can salloc once upon entering
