From "man getrlimit" we have 5 linux-specific constants which are currently not exposed by resource module:

RLIMIT_MSGQUEUE RLIMIT_NICE RLIMIT_RTPRIO RLIMIT_RTTIME RLIMIT_SIGPENDING Also, we have prlimit(), which is useful to get/set resources in a per-process fashion based on process PID. If desirable I can submit a patch for this. --- Giampaolo http://code.google.com/p/pyftpdlib/ http://code.google.com/p/psutil/ http://code.google.com/p/pysendfile/
