Sorry guys, but I think you are completely wrong.

NO no no. The behavior of reading /event in wmii-3 and
wmii-current is equal. Reading /event means reading a file which
never ends, thus the read is blocking until a new event occures.
I think you misunderstand the code, though it's true that my
wmii-3.x fs.c implementation is a nightmare. Kris' wmii-4 fs.c
implementation is much better in many decisions. However, on the
9P level there is no difference!!!!

Sorry, this is not true. No events are lost. Maybe there is a
bug somewhere else, but events are send to all connections which
have opened /event.

Please don't consider using arbitrary crap like bus protocols.
NO EVENT IS LOST. If so, the problem must be somewhere else.
