An update: I ran this by hand:

$ sudo su - cuirass -s /bin/sh -c
"/gnu/store/z8haznhwck4bjm4gxqy25wvwv4041wvx-cuirass-1.1.0-12.f087aaf/bin/cuirass

… and attached ‘strace’, which shows things are working as intended:

The question to me becomes: why is ‘guix repl’ not getting EOF from its
read(0, …) call?
FWIW, here’s an estimate of the amount of data transferred from the
inferior to the main process:
--8<---------------cut here---------------start------------->8---
$ grep 'read(228, .* = 4096$' <log.evaluate|wc -l
25807
--8<---------------cut here---------------end--------------->8---
I’m trying to reproduce that synthetically.
