Sorry it does now. My mistake. A lost process hang on it.

I disagree. I would implement the nfs mounts of autofs like autofs handles local
links. That means, instead of mounting the remote directory directly onto /home
it would mount it on /aufofs/host/user.... and then make a link from /home/user
to /aufofs/host/user.
That means, the access will be as fast as Linux can handle symbolic links. If
that is slow, then autofs is slow. But how fast is NFS anyway.
