  Log Message:
  -----------
  Fix handling of changing function return status and checking of cyclic
dependencies
1. Even blocked frame can have a changed return status, so need to
resume delayed caller
2. Due to parallel parsing, when a thread parses a call site, the
callee may still have a UNSET return status, and the callee is being
parsed by another thread. When all threads' work is done, the UNSET
return status is expired, and we need to revalidate delayed work
