Do we know what if any ports actually use procfs?

Quite a lot of software ported from Linux, because it's way easier to change /proc/self to /proc/curproc than to actually write code for using sysctls and such :)

Grepping for curproc in ports reveals x11/keyboardcast, security/beid, net-mgmt/seafile-server, net-mgmt/seafile-client, java/openjdk7, net-mgmt/ccnet-server, mail/dbmail, science/opensph, sysutils/memfetch, devel/RStudio, devel/synfig, devel/clanlib1, devel/clanlib, devel/oclgrind… Typically it's just for finding the current executable binary.

And you can find more on the internet e.g.

Just installed libsigsegv on a machine and the pkg message was: "Note that the stackoverflow handling functions of this library need procfs mounted on /proc."

So... Is procfs actually obsolete then?

I would say use of procfs is deprecated, and your advice (about libkvm etc.) is sound., but it is still used by a number of ports.

Just say it's deprecated as Ed suggested and overall this change is good.
