 I did some test runs today on an Amiga 1200, 68030/40MHz with 64MB. The
 multiuser boot process takes here 8 minutes and 44 seconds, which was less
 than half the time with NetBSD 6.
 In the first tests I reverted /etc/rc to 1.167, but left the _rc_pid
 definition in line 87 in. Otherwise booting will hang (it is needed by
 rc.subr). Results ("new clib" includes your stdbuf changes):
 old clib: 7:00 min.
 new clib: 6:57 min.
 new clib with STDBUFn=L: 6:58 min.
 new clib with STDBUFn=U: 7:01 min.
 The stdbuf change doesn't make a big difference here. But removing the "nop"
 pinger code is already noticable.
 In the next tests I reverted /etc/rc to 1.167 and /etc/rc.subr to 1.93, as
 suggested by Arto Huusko:
 old clib: 3:44 min.
 new clib: 3:38 min.
 So I can confirm that reverting /etc/rc.subr is the key. Would be great to
 find a solution here.
