procs still uses version 0.4.7, but I didn't see an obvious fix in your git commit log.

CC @dalance.

I think this issue was fixed by #27.
But I forgot to update procfs.
I'll release procs with procfs v0.5.0.

@dalance thanks! I can also reproduce this on my machine, so let me know if you want me to test a new version of procs.

[dalance]

I released procs v0.8.2. Could you try it?

[dbrgn]

Yep, works now for me! 🙂 Thanks for the quick fix.

Thanks!
