 The test case is incorrect. PTHREAD_DESTRUCTOR_ITERATIONS specifies a
 lower limit on the number of iterations performed. It is explicitly not
 a hard limit. To quote POSIX:
 
 Calling pthread_setspecific() from a thread-specific data destructor
 routine may result either in lost storage (after at least
 PTHREAD_DESTRUCTOR_ITERATIONS attempts at destruction) or in an infinite
 loop.
