It sounds like my patch would break some existing software, so it probably
doesn't make sense right now.
I'd still argue that the current mechanism has a number of problems, and it
should probably undergo a comprehensive overhaul at some point in the
future.

same machine. However, if a single user ran DPDK applications concurrently
on several different machines, and if the user's home directory was shared
