Postfix kqueue(2) support broken

[Hasso Tepper <hasso@xxxxxxxxx>]

At some time during last months (I can't give exact dates, sry) something 
broke postfix using kqueue(2) (it's default for DragonFly). I've used 
postfix for ages on my machines, now it starts up, is able to receive 
even some mails at best, but stops responding then. I'm able to telnet to 
the port 25, but postfix doesn't respond.

$ ps axl | grep master
    0 27129     1   0 152   0  4908 1756 kqread ILs   ?? 
0:00.01 /usr/pkg/libexec/postfix/master
$

At all kqueue(2) seems to be extremely fragile in DragonFly. There are 
many packages using it probably just via autodetecting it, but there is 
packages known to be broken in DragonFly for ages while built with 
kqueue(2) support. Sysutils/dbus is certainly most notable such one - 
kqueue(2) support works on every BSD except DragonFly.
