Comment (by 0xffea):

 bonefish: thanks for the very helpful comments!

 i tried to correct the style issues and not to use areas in kernel space.

 * create a cache with VMCacheFactory::CreateAnonymousCache
 * use VMAddressSpace->CreateArea and VMAddressSpace->InsertArea to create
 the area in user space

 hope this is the right way to do it. not sure about the proper locking.
