csup ends up in sigwai after "Shutting down connection to server", never exits

[Anton Shterenlikht]

On ia64 r235474 and r235163 I get: 

# csup -L2 /root/ports-supfile 
Parsing supfile "/root/ports-supfile"
Connecting to cvsup.uk.FreeBSD.org

csup never exits.

On amd64 r236740M I don't see this problem.
