   From what I understand, a background process will automatically
block when it tries to read from STDIN.  By definition, processes
become bg-processes by using '&'.  I haven't looked at the
code, but I'm guessing that the first 'ssh' that you launched
(*without* the '&') is the process swallowing your input as
it was declared to be a some sort of master-multiplexer for
subsequent slave processes, but that's just a guess.  Maybe
putting the master in background @ launch (using '&') will
cause it to auto-block(suspend) as you expect?
