I saw that this was committed to HEAD yesterday. I have a machine with a
8169-based NIC that is doing ~300GB on a daily basis that I'd love to try to
run with debug.mpsafenet=1. Do you think the patch that went into HEAD has
been tested enough that it is safe to try it?

It's a UP machine using POLLING mode (HZ=2000), if that makes any
difference.
