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