_pt_thread_death_internal(), which is part of Linux's nptl pthreads implementation, calls free() after calling TSD destructors.  This was causing a crash during thread exit, since the magazine rack was no longer valid for the thread.  Fix this by using a special mag_rack value to indicate that deallocation should bypass the magazine machinery.
