Completely (?) unrelated, but I have a problem with 1.4.2 where a device
connected to a serial port of this NetBSD system is suffering from data
input timeouts.  The device has a character timeout of 500 ms (if no chars
arrive in that time, the transfer times out).  Hard to believe it, but
this happens - not too often when the NetBSD box is almost idle, but it
happens all the time when NetBSD is running tar+gzip, for example.

I _think_ I didn't see this problem right after rebooting, but I don't
understand what could change the behaviour later.

(Even more unrelated: I'll lose a nice uptime of 434 days on my Sparc/NetBSD
because we're moving, sniff ;-)
