The obvious way to implement an NSURLHandle cache is to use the NSURL as a key to an NSDictionary. However,
this leaks gobs of memory because NSURL doesn't implement hash and isEqual:.

To fix, add these two methods to the NSURL implementation:

- (BOOL) isEqual: (NSURL *)other
{
    return [[self absoluteString] isEqualToString:[other absoluteString]];
}

- (unsigned) hash
{
    return [[self absoluteString] hash];
}
