The rsh command appeared in 4.2BSD.  SSH is a secure replacement for
it.  The rsh man page includes the following in the bugs section:

  Stop signals stop the local rsh process only; this is arguably wrong,
  but currently hard to fix for reasons too complicated to explain here.

And therefore we know that this behavior has always been present.

Although this functionality would be nice to have the implementation
isn't completey straight-forward.  There is an open bug tracking this
behavior request and a patch in the tracker exists about it.
