Correct me if I'm wrong, But can't you technically make any code
'thread-safe' by using Critical Sections before doing work.
I don't think so.
If the function, for example stores some important data in a thread
local variable, but flags (thread global) the availability of the data,
then no Critical section will fix it.
Admittedly this is a constructed case, and sounds like an extremely poor
implementation... But it shows that thread-safety is more than just a
Critical Section. After execution of a thread-save function the overall
state of your app (and the entire system) must still be valid (and it
must be so, for each thread).
