    udevd - Big memory and thread cleanup
    
    * Adjust read_xml() to allocate just the right size of memory, so we
      don't waste anything by allocating 12 MB per client, when the usual
      client xml is a few kB.
    
    * Detach threads so that they can free resources whenever they return
      from their startup function.
    
    * Release the memory associated with a particular iterator and with some
      of the fields in the event filters, which were previously leaking.
    
    * Let the monitor thread check every few (2) seconds if the underlying
      connection is still alive. Previously the threads were staying around
      even after the connection was closed when no event (attach/detach)
      occured.
    
    * Clean up the pdev array on a clean exit so it's easier to find memory
      leaks, since the amount of allocations done by proplib on behalf of
      the pdev stuff is huge.
    
    * Incidentally, don't forget to update the pdev array when a device is
      detached.
