Can bogofilter run by multiprocess at the same time

[陈治璋]

Yes, I have done that. I used a mutex to ensure there is only one
bogoiflter process running at any time. The performance is not bad. But
sometimes when there are many emails, some clients may timeout although
the timeout is as long as seconds. And the load of the central machine
is not very high : load average 9.00, idle 66%. So I think it's because
that only once process can make the full usage of CPU.
