The change wasn't supposed to change observable behavior, so no change 
in Eshell should be required.

I wish someone could help me reproduce it though.

  make -C test lisp/eshell/esh-util-tests

finishes just fine over here, no matter how many times I try. Is it 
perhaps OS-specific? I'm testing this on GNU/Linux now, whereas 
something like macOS might plausibly go down the 'else' clause 
read_and_insert_process_output more often...
