Only a guess, but I predict that it will work for your purposes, since you're not concerned about what happens to std_in et al.
I actually am concerned about what happens to std_in. The parent process serializes a bit of state and passes it to the child via the child's std_in. There's probably a better way to do such a thing, but it works for now.
That statement in the documentation is ambiguous, so if it isn't convenient to just test for this, you need someone to clarify what "doesn't work" means.
I will wait to test this when (and if) I have to put a node on a Windows box.
Sure! At least from a POSIX perspective, and it would be surprising if a Haskell implementation failed to preserve that.
If only I knew for sure that all nodes would remain in the POSIX world. I appreciate the help. --Jonathan
