+// This provides a set of test functions for TLS variables.  The
+// functions are called by a main function in tls_test_main.cc.  This
+// lets us test TLS access from a shared library.  We currently don't
+// bother to test TLS access between two different files, on the
+// theory that that is no more complicated than ordinary variable
+// access between files.
+
+// We start two threads, and stop the second one.  Then we run the
+// first thread through the following cases.  Then we let the second
+// thread continue, and run it through the same set of cases.  All the
+// actual thread manipulation is in tls_test_main.cc.
+
+// 1  Access to an uninitialized global thread variable.
+// 2  Access to an uninitialized static thread variable.
+// 3  Access to an initialized global thread variable.
+// 4  Access to an initialized static thread variable.
+// 5  Taking the address of a global thread variable.
+// 6  Taking the address of a static thread variable.
+// 7  Verify that the above tests left the variables set correctly.
