This class defines an object that provides exclusive access to the critical sections defined by this component's macros.
Declared in <bslmt_testutil.h>
class TestUtil_Guard;
Multiple Guard objects can exist at once, but only in the same thread -- if an attempt is made to construct a Guard while any Guards exist in other threads, the constructor will block until all Guard objects in other threads are destroyed. The behavior is undefined if a Guard object is anywhere but on the stack.
