I have tested it on NetBSD/i386. The "normal" case works well, and I 
have also simulated the situation when getgroups() should return -1. The 
effect is that the return value will never be 1 in that case.

But as the only possible failures are EFAULT (wrong address) and EINVAL 
(ngroups out of range) on Linux, Solaris and NetBSD (and probably most 
others), this should not occur anyway.
