Interesting. The server is supposed to use the SO_KEEPALIVE socket
option to detect broken connections; I wonder why it's not working. And
note that kill -9 should be the last resort for dealing with hung
processes, not the first resort.

I'm not surprised -- you're creating and deleting lots of directories
and small files, so you're doing a lot of directory manipulation which
requires synchronous I/O on a UFS file system and thus is very slow.
