What makes you think this is not a problem upstream?

You're right, I should post this bug upstream. Sorry for the inconvenience.

More of a wontfix than invalid really (maybe we should add something like "third party to resolve").

After reporting this issue upstream the developer was unable to reproduce my problem, so there was not much he could do.
I have made one small change in the code of main.c that solved my problem and would like to share it with anyone who encounters this issue.
The developer has been informed, but I never got an reply on my question if this change was acceptable or not.
See the attached patch sunwait-main.c.diff for the change.
