             Summary: Bootstrap process isn't thread-safe
                 Key: CLOWNFISH-78
                 URL: https://issues.apache.org/jira/browse/CLOWNFISH-78
             Project: Apache Lucy-Clownfish
          Issue Type: Bug
            Reporter: Nick Wellnhofer


The Clownfish bootstrap process isn't thread-safe. For a lock-free solution:

- Class_bootstrap must set the global class pointer at the very end, possibly destroying the
class if another thread set the pointer before.
- The runtime inheritance cycle detection must be reworked, or simply left out. It only protects
from a really contrived scenario.
- Probably other things I missed.

We could also consider a global lock using a locking facility provided by the host language.
