This hadn't occurred during my testing, but I can see the logic of it.
I've now added a test and fixed this; it will be in the next release.

That sounds rather more specific than is needed for the generic
library being proposed here. I'm wary of adding features to an API
that is already quite complex.
Isn't setting the EUID and EGID something that is just as easily done
*after* the program achieves a daemon process?
