  put!(rr::RemoteChannel, args...)

  Store a set of values to the RemoteChannel. If the channel is full,
  blocks until space is available. Return the first argument.

This is expected behavior - the channel you’ve given the RemoteChannel can only hold one item, so it blocks until the channel has space again.
