Pull request overview

This PR modernizes several OS-level interactions in rda_python_common by replacing shell command pipelines (e.g., ps, grep, md5sum, more) with Python-native implementations (psutil, hashlib, subprocess) and bumps the package version to 2.1.11.

Changes:

• Replace ps/grep-based process discovery and child enumeration with psutil in PgSIG.
• Replace md5sum subprocess calls with a streaming hashlib.md5() implementation in PgFile.
• Update usage display and specialist home lookup logic to avoid shelling out (more, /etc/passwd parsing), plus dependency/version bumps.

• check_process() treats any OSError from os.kill(pid, 0) as “not running”. On POSIX, EPERM means the process exists but you don’t have permission to signal it, so this will incorrectly report live processes as dead. Handle PermissionError/errno.EPERM as running and only return 0 for ProcessLookupError/errno.ESRCH (and possibly treat other errors conservatively/log them).

      try:
         os.kill(pid, 0)
      except OSError:
         return 0
      return 1
