Comment (by Chris Kingsley <chris.kingsley@…>):

 By the way, it might be worth noting that this isn't pretending to be an
 *atomic* test and set.  There are specific machine instructions that do
 test and set atomically, used for synchronization.  I don't think
 dynamic_bitset should consider being used as a synchronizer, so it
 shouldn't use the slower atomic operations.
