SharedPtrRegistry_all.wait_lookup_or_create fails inconsistently
I noticed via the gitbuilders that this unit test is inconsistently failing. I can run it repeatedly on my dev box and get intermittent failures with the same binary. I assume there's a race in the test code of some kind rather than the SharedPtrRegistry actually being broken.
common: move SharedPtrRegistry test after t.join
The thread created to test SharedPtrRegistry race conditions updates a
value ( ptr ) that is tested by the main gtest thread but is not
protected by a lock. Instead of adding a lock, the main thread tests
the value after pthread_join() on the child thread.
