Supplementary groups

[Andrew Walrond]

Is there a function for setting supllementary groups? I don't see a method
documented in Process.

I want the equivalent of man (2) setgroups:

- Function: int setgroups (size_t COUNT, gid_t *GROUPS)
This function sets the process's supplementary group IDs. It can
only be called from privileged processes. The COUNT argument
specifies the number of group IDs in the array GROUPS.

Don't believe it was there for Ruby 1.6, but in Ruby 1.8 it's just:

Process.groups = [gid1, gid2, ...]

where the gidx values are either group numbers or names.

Hope this helps,
