I think the problem was basically this:

I cd to a directory which forces a mount from a remote machine, which is
hung or slow. autofs goes off to mount it.
Another user opens a file which forces another mount. The automounter,
however, is blocked serving the former request.
Both requests sit until the first times out. Then the second request is

Then it shouldn't be a problem.
