I agree with Pavel that extending the clone syscall is a better idea than this patch set. The flexibility that Josh and Gabriel talk about seems wholly unnecessary. In every use of fork-(do stuff)-exec I've ever seen, the below two observations remained true: 1. Everything needed in the "do stuff" part was known prior to the call to fork 2. Any failures in the "do stuff" part would scrap the child process and report an error to the parent process
