On second thought, it seems that the mutex in alloc.c don't have to be
recursive regardless of your patch, because _realloc_internal only
calls "hookless" versions of malloc/free (i.e., _malloc_internal and
_free_internal).  Could you try just replacing

  pthread_mutexattr_t attr;

  /*  GLIBC has a faster way to do this, but lets keep it portable.
      This is according to the Single UNIX Specification.  */
  pthread_mutexattr_init (&attr);
  pthread_mutexattr_settype (&attr, PTHREAD_MUTEX_RECURSIVE);
  pthread_mutex_init (&alloc_mutex, &attr);

in uninterrupt_malloc with the following one?

  pthread_mutex_init (&alloc_mutex, NULL);
