those systems are broken.  has nothing really to do with ptrace06.  if you 
want a clean method to handle it, then the autoconf route discussed is the 
way to go.

your understanding of vfork (and thus the test) is incorrect.  read the 
*entire* description of vfork instead of the first sentence.

that's what we call *a bug*.  fix it instead of just saying "oh it's broken 
lets forget about it".  the code already attempts to kill all of its children 
as can be seen clearly in the ptrace06.c at the end.  and it works fine on my 
x86_64 systems.
