docs: Sets the maximum number of bytes a connection may have pending in the disk
  write queue before its download rate is being throttled. This prevents
  fast downloads to slow medias to allocate more memory indefinitely.
  This should be set to at least 16 kB to not completely disrupt normal
  downloads. If it's set to 0, you will be starving the disk thread and
  nothing will be written to disk. this is a per session setting.
  <p>
  When this limit is reached, the peer connections will stop reading
  data from their sockets, until the disk thread catches up. Setting
  this too low will severely limit your download rate.
