help('threading') ......     class Barrier(builtins.object)      |  Implements a Barrier.      |        |  Useful for synchronizing a fixed number of threads at known synchronization      |  points.  Threads block on 'wait()' and are simultaneously once they have all      |  made that call.

So the above text is missing a verb. Do you want to say :   Threads block on 'wait()' and are simultaneously running once they have all made that call or maybe you want to have another verb there? Like exiting ? or executing ? or stopped ? Or maybe you want to say    Threads block on 'wait()' and are simultaneous once they have all made that call. Georgios Doumas
