Example on using resourcelimit module to enable core dumps from Python

coredump.py

from optparse import OptionParser
from time import sleep


def do_something():
    while True:
        print "I'm doing something"
        sleep(5)


if __name__ == '__main__':
    parser = OptionParser()
    parser.add_option('--dump-core', action='store_true', dest='dump_core', default=False)
    options, args = parser.parse_args()

    if options.dump_core:
        print "Core dump enabled"
        import resource
        resource.setrlimit(resource.RLIMIT_CORE, (-1, -1))
    do_something()
