Reproduce -

for proc in psutil.process_iter():
    proc.get_open_files()

Result -
----
Traceback (most recent call last):
  File "/usr/lib/python3.3/site-packages/psutil/_pslinux.py", line 463, in wrapper
    return fun(self, *args, **kwargs)
  File "/usr/lib/python3.3/site-packages/psutil/_pslinux.py", line 908, in 
get_open_files
    files = os.listdir("/proc/%s/fd" % self.pid)
PermissionError: [Errno 13] Permission denied: '/proc/1/fd'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "./singleton_script.py", line 6, in <module>
    proc.get_open_files()
  File "/usr/lib/python3.3/site-packages/psutil/__init__.py", line 808, in

    raise AccessDenied(self.pid, self._process_name)

Agreed. I've been unhappy with this for a while.
2.0.0 is the right chance to change this.

I killed long deprecated errors.py and _errors.py modules in revision 
c001b5f9a258 .
Exception classes now live in "psutil" namespace only.
Closing and thanks.
