What steps will reproduce the problem?  
<snippet>
import psutil

n = 0
for p in psutil.process_iter():
    try:
        n += p.get_memory_percent()
    except:
        print p.pid
        print p.name
        raise
print n
</snippet>

raises:

D:\pyftpdlib\svn\psutil>foo.py
944
csrss.exe
Traceback (most recent call last):
  File "D:\pyftpdlib\svn\psutil\foo.py", line 10, in <module>
    n += p.get_memory_percent()
  File "D:\pyftpdlib\svn\psutil\psutil\_psutil.py", line 250, in
get_memory_perc
ent
    rss = _platform_impl.get_memory_info(self.pid)[0]
  File "psutil\_psmswindows.py", line 29, in wrapper
    raise AccessDenied
psutil.error.AccessDenied


csrss.exe is owned by the SYSTEM user, I'm running the script as Administrator.

Fixed, needed to set SE_DEBUG privilege first. I decided to just set this once in the
init of the module since it's needed all over the place for anything that reads data
for a process owned by another user.

Status: Fixed

Updated csets after the SVN -> Mercurial migration: r304 == revision ???
