That would be really sad if it were true, Nate.
Not the absurd numbers, mind you, but changing this should be as easy as
modifying any other system parameter.
I used to have to change things like PAGE_VHAND_FREE on SCO and Ultrix, and
NGROUPS_MAX is the same kind of fish, it seems to me.

That said, acls(whatever that is) might be a more portable solution than
reconfiguring your libc6. :)
