Bug 49504

GemStone/S 64 Bit

Symbol GC slow with many dead symbols

When Symbol GC finds a very large number of possible dead symbols, the write set union sweep became unreasonably slow.  This was a result of the possibleDeadSymbol structure containing large collision buckets; the objects referenced from the collision buckets were being read, which is unnecessary, since all contained objects would be symbols.
