ApicIds deadlock

See ​call stack (from Brian), particularly:

The first ModuleInit call locks the state while calling init() which then tries to lock the state itself.

(In [7852]) fix deadlock in pre-XP SP2 windows codepath fixes #525

[philip]

(In [7853]) Fix #525 more, so it doesn't use an uninitialised variable
