[Bug nptl/378] posix_spawn implementation, use vfork/execve rather than fork/execve for NPTL Linux.

Well spotted.

I guess application developers will need to know how 
each posix_spawn implementation deals with atfork handlers.
The Solaris 10 man page indicates clearly what they do. 

If a change does occur in the NPTL glibc posix_spawn (fingers
crossed), again the man will need to state clearly what happens
in each situation (fork/exec path and possible vfork/exec path).

It does appear that a vfork-path based posix_spawn which 
does not run atfork handlers will be safe, fast and 
standards complient.
