I think he meant shared first/last:

static shared this(){}
static this(){}//main thread
static this(){}//thread x
...
static ~this() {}//thread x
static ~this() {}// main thread
static shared ~this() {}

...which is (as Kagamin suggested) similar to they way DLLs are 
(de)inited on Windows.

vote++ by the way.
