+1 Some white space nits, but other than that, looks great.

    Move to top of file with other val declarations (timeout, 
depletedQueueSizeThreshold, etc).
    
    Add a debug() line printing computed backoff.
    
    Also, seems kind of error prone to depend on this being lazy. Can we just 
compute in .start(), after fetchmap is guaranteed to be fully computed? Would 
require setting to var, which is annoying.

    delete extra \n.

    leave \n spacing here.
