Ancestors: System-cmm.602
- Restore unused 'size' instVar as the last slot of RecentMessages. Trunk update started crashing the VM! The new RecentMessages>>suspendWhile: is invoked during the update process, so by changing the shape of RecentMessages to remove 'size', the reference to last inst-slot, 'isSuspended' causes mayhem.
