Re: Introduce posix_spawn

Something I haven't heard explained on this thread yet is why the
change would be worthwhile in terms of cost (to e.g. the GNU project)
vs. benefit (to e.g. users).

The cost is, I hope, reasonably obvious:
 - the maintenance burden of the extra code and maintaining both
fork/exec and posix_spawn implementations.
 - the cost to users of the additional bugs introduced by human error
during this maintenance

Benefits on the other hand probably accrue mainly to users (which is fine):
 - but actually, what are those benefits?
 - are those benefits enjoyed by users other than Threos users?  Who?
 Would this e.g. work better for Cygwin?
