There is another option - even if the server does not close after
sending: use #read with a given size limit. #read will block and
return as soon data is available.  Using #read without limit is a bad
idea on a socket anyway because it has to read until EOS, as you
indicated.

DRb would be another option if both sides are written in Ruby.
