No. `static` in this case means the lifetime is the lifetime of the module. By default, a static variable would be in TLS and would have the lifetime of the thread that it was instantiated in (and there would be one instance per thread). `__gshared` is needed to coax the compiler into making the variable global in the C/C++ sense, i.e., only 1 instance across all threads. tl;dr: C static == D __gshared.
