   6  *   This program tests the interaction between TSS and thread keys
   7  *   created during static construction.  VxWorks static construction
   8  *   is quite broken.  This test is designed to test changes to work
   9  *   around a bug in the VxWorks loader that constructs static objects
  10  *   multiple times.  It sounds hard to believe, but I've seen it!
