+ &man.geom.4; got I/O direct dispatch support.
+ When safety requirements are met, it allows to avoid passing
+ I/O requests to GEOM g_up/g_down thread, executing them directly
+ in the caller context. That allows to avoid CPU bottlenecks in
+ g_up/g_down threads, plus avoid several context switches per I/O.
