* As for mutex1.c but with type set to PTHREAD_MUTEX_RECURSIVE.
*
* Create a simple mutex object, lock it, unlock it, then destroy it.
* This is the simplest test of the pthread mutex family that we can do.
*
* Depends on API functions:
* pthread_mutexattr_settype()
* pthread_mutex_init()
* pthread_mutex_destroy()
