Geez, I certainly hope no English teachers ever see that paragraph.

This has been tested by several other -CURRENT users with no issues, so be 
certain to report any as they come up.  There shouldn't be much software 
which has to be recompiled, outside of the base system.  The resolver(3) 
interface is not very portable, so usage of the _res structure should be 
relatively rare, and threaded programs should already be using 
getaddrinfo(3) and getting error returns via that API, and not via
h_errno.
