Comment (by jeremyfelt):

 [attachment:27003.16.diff] builds on Nacin's [attachment:27003.14.diff]
 and adds caching for requests made to `get_network_by_path()`. Keys are an
 md5 hash of the requested domain and path, along the same lines of the key
 creation in `WP_Theme`.

 {{{
 $request_cache_hash = md5( $domain . '/' . $path );
 $network_id = wp_cache_get( 'network_' . $request_cache_hash, 'networks'
 );
 }}}

 I'm not sure where invalidation would be needed here. This is a cache of a
 specific request and for it to become invalid, the network ID matched with
 the domain and path would have to change. This doesn't seem too common,
 though we can clear or reset the cache value way down the road when some
 sort of network management appears in the admin. Maybe?
