 The size increase is not really necessary if you are willing to
 pay the cost of going through the all_thread list when you remove
 a key (and hold a different lock). Having said that, even in the
 case of 1000 threads, this just amounts to 6M of memory on a 64
 bit host, instread of ~2M, since I've added 2 pointers to the array
 of 256 keys; you need at least one more to hold the data.
