Answer 1

If you know the number of subprocess ahead of time, it might be reasonable to pre-fork your application on startup then distribute the execv information via a pipe. Alternatively, if there is some sort of "lull" in your program it might be reasonable to fork ahead of time a subprocess or two for quick turnaround at a later time. Neither of these options would directly solve the problem but if either approach is suitable to your app, it might allow you to side-step the issue.
