These shouldn't be hard-coded into user-land programs.  Instead we should 
have a mechanism for getting the numbers from the kernel.  Then machines 
can set these as appropriate and user-land binaries will continue to work 
correctly.  This information could easily be made available via the 
sysctl(3) interface.
