An alternative is to have the execve happen in a callback, similar to the
following patch I posted a couple months ago:
http://marc.theaimsgroup.com/?l=linux-kernel&m=109871749900732&w=2
IMHO, this is a better interface as it allows module writers to make arbitrary
changes.
(Some interface for allowing modules to 'safely' do execve is still required
though).
