Perhaps the right thing to do is to have GeolocationService::create  
make the appropriate platform-specific service class, so that the core  
code can remain platform-independent and platform ifdefs can be  
limited to the platform/ directory.

There's not necessarily a conflict there - often the right thing to do  
under our refcounting rules is to pass raw pointers, if the callee is  
not expected to take ownership. (See Darin's document <http://webkit.org/coding/RefPtr.html

is wrong?
