But this does not break unrelated software as the code that uses it has
to be inserted deliberately, making it no longer unrelated. In a way,
this is a stronger restriction than the usual linking arguments pushed
by the FSF, but it's not totally crazy. In some jurisdictions even
copying a program into memory by an exec(3) call is an action for which
you need the permission by the rights holder.
