2. RtlGetVersion needs to be implemented differently in ntoskrnl and ntdll, ntoskrnl's version must not access the PEB (which might not be present) while ntdlls gets most information from the PEB structure 3. can't use spinlocks to serialize access to the security descriptor cache since it calls sd rtl functions which require to run < apc level svn path=/trunk/; revision=13712
