Is there any interprocess barrier/latch?

Hello:

thanks for this awesome library. I just wonder, is there any interprocess latch or barrier to sync several processes? I found some old document but they are not in current version of boost::interprocess.

Reviewing old bugs. Thanks for your kind workds. No, sorry they were removed because they were buggy and not working properly, there is no plan to bring them back.
