+/** Thread local storage.
+
+   A minimal wrapper that should be implementable across many compilers,
+   and implementable efficiently across most modern compilers.
+
+   Thread locals have type intptr_t.
+
+   Declaring a thread local variable 'foo':
+     GPR_TLS_DECL(foo);
+   Thread locals always have static scope.
+
+   Declaring a thread local class variable 'foo':
+     GPR_TLS_CLASS_DECL(foo);
+
+   Defining the thread local class variable:
+     GPR_TLS_CLASS_DEF(foo);
+
+   Initializing a thread local (must be done at library initialization
+   time):
+     gpr_tls_init(&foo);
+
+   Destroying a thread local:
+     gpr_tls_destroy(&foo);
+
+   Setting a thread local (returns new_value):
+     gpr_tls_set(&foo, new_value);
+
+   Accessing a thread local:
+     current_value = gpr_tls_get(&foo);
+
+   ALL functions here may be implemented as macros. */
