As Ivan said, it is typically a bash shell or some program that was
started while the cwd was somewhere in /coda. The current working
directory pins down the directory cache entry in the kernel and it
refuses to unmount. (this happens in the VFS and is out of our control).

The easiest way to find these processes is,

    lsof | grep '/coda'

(venus isn't running, so lsof /coda won't work as lsof can't stat the
mountpoint anymore).
