But this is what a C/C++ compiler would do, unless you your data
is qualified as volatile. I believe __gshared also implies the
volatile behavior, right? I wouldn't make sense any other way.
So basically, __gshared is like saying "I want the C/C++
behavior, and I accept I am all on my own as the compiler will
not help me".
