    During VM oom condition, kill all threads in process group · dcca2bde
    Will Schmidt 提交于
    We have had complaints where a threaded application is left in a bad state
    after one of it's threads is killed when we hit a VM: out_of_memory
    condition.
    
    Killing just one of the process threads can leave the application in a bad
    state, whereas killing the entire process group would allow for the
    application to restart, or be otherwise handled, and makes it very obvious
    that something has gone wrong.
    
    This change allows the entire process group to be taken down, rather
    than just the one thread.
