To quote Stephen McKay: pmap_copy is a complex NOP at this moment :-).
With this fix from Stephen, we are getting the target fork performance that I have been trying to attain: P5-166, before the mega-commit: 700-800usecs, after: 600usecs, with Stephen's fix: 500usecs!!! Also, this could be the solution of some strange panic problems... Reviewed by: dyson@freebsd.org Submitted by: Stephen McKay <syssgm@devetir.qld.gov.au>
