Bug Description

Binary package hint: landscape-client

My /var/log/landscape/sysinfo.log has twelve tracebacks like this:

2010-02-05 11:10:01,929 ERROR Processes plugin raised an exception.
Traceback (most recent call last):
  File "/usr/lib/python2.6/dist-packages/landscape/sysinfo/sysinfo.py", line 98, in run
    result = plugin.run()
  File "/usr/lib/python2.6/dist-packages/landscape/sysinfo/processes.py", line 18, in run
    for process_info in info.get_all_process_info():
  File "/usr/lib/python2.6/dist-packages/landscape/lib/process.py", line 45, in get_all_process_info
    process_info = self.get_process_info(process_id)
  File "/usr/lib/python2.6/dist-packages/landscape/lib/process.py", line 116, in get_process_info
    parts = file.read().split()
IOError: [Errno 3] No such process

I assume there's a race condition in landscape.lib.process: the process can exit between "get a list of valid PIDs" and "query information about the PID".
