Owen Anderson 0b7401d3cd Ease contention on this lock by noticing that all writes to the VTs array will ...

be of (dynamically) constant values, so races on it are immaterial.  We just need
to ensure that at least one write has completed before return the pointer into it.

With this change, parllc exhibits essentially no overhead on 403.gcc.
