Condy bsm should be idempotent

This is going to be problematic for bootstraps that produce, e.g., 
arrays; their equals() method delegates to Object.equals(), which means 
such bootstraps would have to maintain an (expensive!) cache for interning.

It is an old problem that constant resolution can be racy, but we would 
like for the JVM to manage the race, not the bootstraps.
