Hmm. I have a local net of 8 machines, and I don't have any such
problems. Of course you know about "set afilter".
The thing I don't understand is how re-writing anything is going to
solve a problem where people want the link to shutdown subliminally :-)

Agreed.

You've been working w/ Windoze too long !!! You're becoming a
heretic !
Perhaps that idea warrants some sort of ability to do a select() on a
seekable file. If you've got the O_APPEND flag, select will return
when there's more data at the end (tail(1) would be almost perfect).
When you haven't got O_APPEND, maybe a file update would wake up the
select().
Of course the implementation is trivial ;-I (not)
