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.
