I was looking at adding kqueue support as well when I wrote the inotify 
implementation.  However, the kqueue API is so bad that it makes even the w32 
API look good in comparison.  (kqueue is probably also the reason why the 
gfile API is so limited compared to inotify.  They simply can't implement a 
lot of it on BSD.  We all have to suffer because of kqueue even if we use 
saner systems.)

Maybe on GNU/Linux the default could be set to inotify or would this break 
using gfile on remote systems via tramp?
