Open or not open, that is the stupid question.

Just read an article mentioned about the reversions of git, so take a note here.

We could limit memory usage in Python program. #!/usr/bin/env python3.5 import resource def show_memory_limit(): soft, hard = resource.getrlimit(resource.RLIMIT_DATA) print 'Soft limit changed to :', soft print 'Hard limit changed to :', hard def set_memory_limit(soft, hard): resource.setrlimit(resource.RLIMIT_DATA, (soft, hard)) #limit to one kilobyte if __name__ == '__main__': show_memory_limit() set_memory_limit(1024, 2048) show_memory_limit() Wish this helps. regards, Stanley Huang
