CDBEnv::Shutdown calls OutputDebugStringF if there is an error closing the database.

The database environment is a global variable.

OutputDebugStringF contains a static boost::mutex.

C++ does not guarantee an order for the destruction of static/global objects, and I am getting a crash I assume because at shutdown (I'm testing handling of corrupt wallet files):

the static mutexDebugLog is destroyed
THEN the bitdb CDBEnv is destroyed, calling printf (OutputDebugStringF), which then crashes calling scoped_lock(mutexDebugLog)
