Ned Deily <nad at acm.org> added the comment:
"It could be a feature of os that the groups of the user are set on a os.setuid call? Or would this break compatibility with the standard unix library behaviour?"
The POSIX system interface specification specifically prohibits that: "The setuid() function shall not affect the supplementary group list in any way."
