Well it was Solaris so it didn't have the BSD 30s sync style strategy. But
this was a large NFS file transfer to another host on a 100Mb/s network. In
30s there could be a lot of writes buffered up.
I'm not saying the behaviour was ideal, and I don't know exactly why it
interfered with anything else. But I'm not entirely surprised either.
