NFS tests fail

[Martin Husemann]

In -current all(?) NFS tests started failing:

    nfs_extendfile: [0.396107s] Failed: child died
    nfs_extendfile_append: [0.420483s] Failed: child died
    nfs_holywrite: [0.370887s] Failed: child died
    nfs_overwrite512: [0.407758s] Failed: child died
    nfs_overwrite64k: [0.381165s] Failed: child died
    nfs_overwrite_trunc: [0.400281s] Failed: child died

Just a heads up - anyone has an idea what change did trigger this?
