 We should wrap DISPATCH_SOURCE_TYPE_VNODE

 http://developer.apple.com/mac/library/documentation/Darwin/Reference/ManPages/man3/dispatch_source_create.3.html

 file_source = Dispatch::Source.for_file(queue, io, mask, &block)

 As with PROC, the key is coming up with the right "bitfield" class to
 represent the event types:

            o DISPATCH_VNODE_DELETE  The referenced node was removed from
 the filesystem namespace via unlink(2).

            o DISPATCH_VNODE_WRITE   A write to the referenced file
 occurred

            o DISPATCH_VNODE_EXTEND  The referenced file was extended

            o DISPATCH_VNODE_ATTRIB  The metadata attributes of the
 referenced node have changed

            o DISPATCH_VNODE_LINK    The link count on the referenced node
 has changed

            o DISPATCH_VNODE_RENAME  The referenced node was renamed

            o DISPATCH_VNODE_REVOKE  Access to the referenced node was
 revoked via revoke(2) or the underlying fileystem was unmounted.

 e.g.,: Dispatch::Source::FileEvent.new(:delete, :write, :extend, :attrib,
 :link, :rename, :revoke)
