If it does a fork and exec then it could be called fork-exec :).

The old DOS systems used to use "spawn" for that sort of thing I think
(spawnl, spawnle, etc like the exec functions).

Either way, if it can get the errno back to the parent when exec fails
(and use _exit) then it'd be a nice improvement over a fork and exec
one might write explicitly.  (A close-on-exec pipe is a good way to do
