Anecdotally speaking, Most users will encounter bottlenecks
due to exclusive locks on pgss hash ( dealloc and garbage collection )
more often than they will on the spinlock. The spinlock will likely
become more of an issue when you are not seeing much dealloc/gc
and running on a very large machine. So, I don't think it's a non-existent
problem, but I don't think it's the most common problem.
