-** This hack brought to you so we can handle set[ug]id MH programs.
-** If we return -1, then no fork is made, we update .mh_profile
-** normally, and return to the caller normally. If we return 0,
-** then the child is executing, .mh_profile is modified after
-** we set our [ug]ids to the norm. If we return > 0, then the
-** parent is executed and .mh_profile has already be modified.
-** We can just return to the caller immediately.
