Hi,

I'm going to add a "me too" to this. I've had the problem on both 
3.4-STABLE, and 4.0-CURRENT. I haven't checked before what state anything 
was in (i will next time it happens). My FreeBSD machine doesn't even have 
a keyboard/monitor, so i don't know if it happens when i'm not telnetting 
to it.

Basically, the make stops, and the telnet becomes unresponsive. I have to 
manually disconnect, and then reconnect, only to find a bunch of make's etc 
sitting in 'ps'. Sometimes they keep going (!?), sometimes they dont.

Also, some telnet sessions mysteriously freeze (they like to freeze during 
cvsup). Wondering what's going on, i press a key, and then everything 
floods in and i realise that cvsup finished ages ago.

I'm telnetting to my FreeBSD machine over my LAN, via 'vr0' @ 100Mbps FD.

Cheers
