In general, we've also been encouraging a move to named sysctls from numeric 
constants.  Should we be sweeping the tree to catch remaining uses, and 
possibly be considering hiding visibility of the numeric constants from user 
space by default?  (i.e., #ifdef DEPRECATED_SYSCTL_CONSTANTS).  I assume we'll 
want to continue to support them in kernel for the forseeable future to allow 
old FreeBSD user spaces to continue to run in jails on new kernels.

Just something to think about now 8.x is alive and the life cycle is long...
