I think one of the SPEC2006 tests doesn't have enough statically-allocated VP nodes per site. We're seeing:

It seems like the fix for now is to either tweak vp-counters-per-site for the test or to set -vp-static-alloc=false.
In the long term, do you think it's worth adjusting vp-counters-per-site s.t we can run SPEC without modifications? If so, is SPEC the right testbed?
