commit ba9b0319b00692038e5d4aa2eff7cf5d6947e659

    Shutdown libevent _after_ the subsystems.
    
    This is necessary since shutting down libevent frees some pointer
    that the subsystems want to free themselves. A longer term solution
    will be to turn the evloop module into a subsystem itself, but for
    now it is best to do the minimal fix.
    
    Fixes bug 30629; bugfix on 0.4.1.1-alpha.
