This one i'm not convinced about. At some point, you are going to make
initialisation of MIBs conditional. Why not use that condition to
control removal as well a setup? Why do you need both a conditional
and this pp->mib_init state flag?

This looks odd. When adding an if (), you would expect the next line
to require an additional indent. Was the indentation already wrong?
