I think Al was right. It is outside the scope of this list. I think we have two 
options

1.      Clone works like this [warning Linux specific]
        What is posix.4

2.      Clone works like this [warning Linux specific]
        POSIX.4 works like this 
                The following do not work
                        signal quirks
                        exec quirks
                        setuid quirks

        Relying on the non function of a standard property of POSIX.4 is 
expressely
        forbidden by this specification. Future changes to the Linux pthreads 
library
        to bring them further in line with the specification are explicitly 
defined
        as compliant to the LSB definition.

No software is perfect. If they know the limits they get to make the decisions 
they
need.
