Eitan stated that this was historical in nature for gen1 drivers which
had resource tracking problems: "if OpenSM left without cleaning up all
used resources (like MAD buffers and UD-AVs), the driver oops'ed."

I think that (eliminating the handler for SIGINT) can at least be done
for OSM_VENDOR_INTF_OPENIB and leave it there for the other vendor
layers for starters. I will experiment with gen2 and let you know.
