--- Comment #8 from Thomas Henlich <thenlich at users dot sourceforge.net> 2011-05-14 12:54:26 UTC --- Maybe I'm wrong, but I'm not sure the current implementation of asynchronous execution is very efficient (on Unix systems): We fork() and then call system(), which forks again and runs a shell, then the shell exits, the forked process inside system() exits, the we exit our forked process. I think we might as well just fork and exec the shell directly which would save one process creation. We also don't need the exit value from the system() call in Fortran.
