Linux has a function (prlimit(2)) which allows to get/set resource limits for a 
certain process.

With this you can, say, instruct a process so that it uses no more than a 
certain amount of memory or opens no more than a certain number of files, see: 
http://linux.die.net/man/2/prlimit There's also a proposal for inclusion of 
prlimit(2) into Python 3.4, see: http://bugs.python.org/issue16595 Proposal  
is to provide the same functionality in psutil by providing two new functions 
behaving along these lines:

>>> p = psutil.Process(pid)
>>> p.get_rlimit(psutil.RLIMIT_NOFILE)
(1024, 4096)
>>> p.set_rlimit(psutil.RLIMIT_NOFILE, (5, 5))
>>> p.get_rlimit(psutil.RLIMIT_NOFILE)
(5, 5)
>>>

Basically this would be equivalent to resource's module getrlimit() and 
setrlimit() functions but applicable to any process/pid (as opposed to current 
process only): http://docs.python.org/2/library/resource.html
