Do you mean two processes inserting into the same table?

I committed some changes recently that reduce the amount of contention
involved in that scenario, but it's not released yet.

Another fairly likely issue is the not-very-good implementation of
spinlocks.  We've talked about finding a way other than select() to
block on a spinlock, but no one's done anything about it yet...
