Thanks for the effort, but I'm afraid I am not gonna merge this work for the same reasons given for IBMi (#1564 (comment)), Haiku (#1690 (comment)) and QNX (#2143) platforms.

At a first glance, GNU/Hurd seems even more niche than those platforms. We can't setup a CI for it, you would be the only maintainer, and the number of downloads would be so low that it's not worth the trouble to add (and maintain) the additional 2800+ lines of code to the current source tree.

I think it makes more sense to make this work develop and mature in your own fork. If your fork is good enough, I can list it somewhere in psutil's README or doc.

With that said, I can give you support reviewing your changes. E.g. the first thing I would recommend is to re-use _pslinux.py instead of copying it into _psgnu.py. If GNU/Hurd supports the /proc FS, as it seems, adding support for it should be much easier than you think, as you can reuse _pslinux.py implementation in full, and just add if GNUHURD: ... where necessary. Just to give you an idea:

# _psgnu.py

from _pslinux import *
import _pslinux


def virtual_memory():
    # alternative implementation for virtual_memory()



class Process(_pslinux.Process):
    def name(self):
        # alternative implementation for name()
