When attempting to run eTainter on macOS (currently 13.4.1), it crashes with the following traceback:

Traceback (most recent call last):
  File "/etc/local/eTainter/bin/analyzer.py", line 290, in <module>
    main()
  File "/etc/local/projects/eTainter/bin/analyzer.py", line 254, in main
    resource.setrlimit(rsrc, (mem_limit, mem_limit))  
ValueError: current limit exceeds maximum limit

Actually, this issue is not specific to eTainter but affects Python on macOS as a whole (see [1] and [2]).

I suggest to escape the rlimit modification on non-Linux systems to prevent this kind of issue.
