 Before, I tried doing this by solution (1). One major problem was that
 alot of code depends on the offset of the field after the sync block
 to be 0 mod 8.

+Solution 1 is not applicable, IMHO. Our lock/unlock is already three
+times slower than it needs to be and we need to speed it up, not slow
+it down (especially once we audit the assemblies for thread safeness
+and we'll need to perform more locks than now).
+Doing solution 2 would probably not be too hard since, unlike what ben
+claims, there are just one or two places with the alignment
+assumption, but it basically assumes we'll have a slow lock
+implementation like now where we could add the special case code:
+adding it to the inlined lock/unlock code would be a significant
+complexity.
