This is always tricky but I wonder how far we could get by initializing
ProtectionDomain.debug and SecureClassLoader.debug lazily. That is, move
them to a holder class where I wouldn't expect they will be initialized
until much later, esp. as the security manager won't be set until later
in the initialization (or init phase 3 as we've come to name it).
