[Message part 1 (text/plain, inline)]

Loading the (git) module after a call to (activate-readline) from
(ice-9 readline) stalls my repl, in most (9 out of 10) cases.

Observe:

--8<---------------cut here---------------start------------->8---
$ guile -q

scheme@(guile-user)> (use-modules (ice-9 readline))
scheme@(guile-user)> (activate-readline)
scheme@(guile-user)> (use-modules (git)) (display "This still shows up?")
This still shows up?
;; <- It is stuck here, not even a SIGINT works
[1]+  Stopped                 guile -q
--8<---------------cut here---------------end--------------->8---

I have verified that using guile without any repl does not exhibit this
behaviour. I have attached the `strace -f guile' where I
pipe the offending code into stdin, and then the problem does not seem
to present itself. See "working.log".

I have also attached the strace of the repl when it exhibits the issue;
see "broken.log".

I think this might be related to
http://lists.gnu.org/archive/html/bug-guix/2018-07/msg00170.html as well.
