Log:
Added fast enumeration to NSSet. This changed the layout of GSMutableSet,
adding a _version ivar, but this is a private class so it doesn't change the
public ABI. All mutator methods in GSMutableSet must increment this variable,
allowing thread-safe fast enumeration.
As with GSArray, GSSet uses its isa pointer for detecting mutations. This may
change as a result of adding KVO notifications, so it might not be the best
solution, but I can't currently think of a way we could catch isa changing to
[GSMutableSet class] and not changing to a hidden class...
