Is this more connected with the Kernel or with POSIX compliance? I know that the Kernel is responsible for supporting/implementing POSIX, but is it the support of POSIX that causes the problem or is it  
a not related Kernel issue?  I wonder because I have heard that same phrase in reference to this discussion before about "Unix and its variants" Common thread that I know of in that case is POSIX
