So relying on the well-documented behavior of a system call is a bug? 
Did you even read about the scenario I described at
https://gnunet.org/vfork ? Before writing this, I looked around for 
existing information on vfork, but I didn't find anyone making a good 
argument (or even the claim) that relying on 'suspend-the-parent' was 
per-se buggy.  (Naturally, the result would be non-portable for systems 
where fork==vfork, but then maybe implementing vfork as fork is the bug? 
;-))

Happy hacking
