Loader lock is a recursive critical section so it's OK to do that from the
same thread and actually, the Wine loader code is written to allow that to
work.

That said it's quite dangerous to do much of anything inside a DllMain
because so much stuff in Win32 relies on multiple threads or inter-thread
messaging behind your back.
