System.Process.runInteractiveCommand, exit_group ()

[Johannes Waldmann]

Dear all,

I have a Haskell program (compiled with -threaded)
that calls an external executable via System.Process.runInteractiveCommand
(and then I do waitForProcess).

The external program finishes with exit_group ()
(I don't have source, but I see it from strace).

Then, my Haskell program dies immediately.
Is exit_group () the reason? How can I prevent this?

Thanks - J.W.
