Yeah, I noticed this a week ago I think, on sparc64. I thought it was 
only affecting sparc64 port as they're changing to wscons or something, 
but looks like the bug is somewhere else. I see the same behaviour via ssh:

vmstat -c 10 1

before vmstat finished outputting 10 lines, hit CTRL-C and it will not 
terminate the process
