I think the worst case is skas3 with no stack randomization, where that page will point somewhere into the process stack. There is some slight possibility that something could store a password on its stack, and have that end up in the area that the host ps looks for arguments. This would make the password visible on the host for the time that this process in context. With stack randomization, the UML process stacks will be located elsewhere almost all the time, so with skas3, there is a smaller chance that there will be a visible password there. With skas0, that page is the stub signal stack, which contains no sensitive information.
