You are right in some cases, but look better. Many of those are in fact serialized elsewhere (that is esp. true for heap - that one IS thread safe to my knowledge).

OTOH, you have missed some that might cause a trouble in future (e.g. when working on GuiMT, I have fount that Ptr/Pte are not really thread safe - something to fix ASAP).

Also, note that StaticCriticalSection is zero-initilized POD, so it does not perform any further form of initilization (nice simple solution to "how to serialize initialization of serializer").

Anyway, thanks. I must admit that multithreading is generally less tested / fixed than the rest of library. Any warnings/suggestions here are welcome.
