This is particularly useful for processes that may have several ids if
they belong to nested namespaces.


How do you handle race conditions, i.e. you specify the ID for the
next object to be created, and then some other thread goes and creates
an object before your thread creates one?

Nick.

OK, race problem between threads is fixed. Thanks for finding the issue!

The new patch series is coming next.
