This is a classic Unix problem because pretty much all Unix systems use
a static array for the auxilliary group membership. IIRC the Cobalt/Sun
kernel patch for the dynamic group list went in before RHEL 4 picked the
kernel version, so it should support up to 65536. See the output of:
echo -e '#include <limits.h>\nNGROUPS_MAX' | cpp | tail -1
