A *lot* of time.

Except when there are bugs. For example, sealert has a significant problem
that I've mentioned on the selinux list a number of times: for some AVCs,
it does *not* catch and properly handle some errors which are unknown, and
it falls through to assert that if I want to enable this, I need to set
httpd_unified on... when it's been on, and has nothing to do with that.
