+
+items todo from bill sommerfeld:
+       - multiple entry points
+       - events should remain across fork()
+       - rewrite sowakeup()
+       - use pool for everything. (i'm not convinced)
+       - high-level docco overview of kqueues [c.f jlemon's various papers]
+
+done:
+       - name->id lookup
+       - why is union kn_ptr not just a void *? (added p_opaque)
+       - need more comments in kern_event.c
+       - explain fd_knlistsize better
+       - section 9 man page for internal api
+
+
+merge in from freebsd:
+       usr.bin/tail
+       pkgsrc/devel/py-kqueue
+       lib/libc/sys/kqueue.2
+       lib/libc/net/res_send.c
+       sys/netinet/tcp_subr.c  1.93 (?)
+       libc/libc_r/uthread (?)
+       pkgsrc/security/l0pht-watch (?)
+       pkgsrc/www/thttpd
+
+
+
+general points:
+       - miscfs/fifofs/fifo_* seems to define filters which aren't used
+         by our tree
+
+to fix:
+
+       - look for XXXLUKEM in the comments. these usually indicate
+         areas to either fix or sanity check they're ok (and remove
+         the XXXLUKEM comment)
+
+       - need to test bits of the tree that call closef() to determine
+         if knote_fdclose() is required. (aka fdrelease()/fdfree()):
+               * ktrderef()            ktrace
+               * unp_detach()
+               * nfsrv_zapsock()       nfsd
+               * portal_unmount()      mount_portal ?
+
+not implemented:
+
+       - pipes/fifos
+               named pipes (fifos) don't work.
+               c.f. freebsd's kern/sys_pipe.c. need to integrate with the
+               pipe code that jdolocek has integrated
+
+       - aio support
+               not supported on netbsd; a noop for now
