Sorry for not being 100% precise, I needed to check back with the 
administrators of the file server: There is no automounter involved at all.
At the server side, there is simply a hierarchy of ZFS partitions (because a 
per-user quota has to be mapped to per-partition quotas, so every user got a 
separate ZFS partition) mounted below the NFS-exported directory.

Yes, the process keeps running fine.

Yes, that was also my guess.  But why - is this a limitation we can work 
around, or does this need fixing in the kernel, or is it a fundamental 
problem?

Have a nice day,
