+         Enable this to turn on some debug checking for credential
+         management.  The additional code keeps track of the number of
+         pointers from task_structs to any given cred struct, and checks to
+         see that this number never exceeds the usage count of the cred
+         struct.
+
+         Furthermore, if SELinux is enabled, this also checks that the
+         security pointer in the cred struct is never seen to be invalid.
