-// Test throwing std::bad_alloc
-//-----------------------------
-// Concerns:
-// A Each allocation performed during thread construction should be performed
-// in the parent thread so that std::terminate is not called if
-// std::bad_alloc is thrown by new.
-// B std::thread's constructor should properly handle exceptions and not leak
-// memory.
-// Plan:
-// 1 Create a thread and count the number of allocations, 'N', it performs.
-// 2 For each allocation performed run a test where that allocation throws.
-// 2.1 check that the exception can be caught in the parent thread.
-// 2.2 Check that the functor has not been called.
-// 2.3 Check that no memory allocated by the creation of the thread is leaked.
-// 3 Finally check that a thread runs successfully if we throw after 'N+1'
-// allocations.
