You can move the explicit reference, because the network stack will
automatically set debug.mpsafenet=0 if you compile i4b into it.  I hope to
have some patches to make it more mpsafe in the near future, but am
currently working on other bugs.

I'll probably bother you again in a few weeks with some patches to try
:-).
