You’re right about --verbosity=4 interrupting builds, I get:
Toggle snippet (25 lines)
$ guix build --verbosity=4 vim --no-substitutes

IOW, the debugging message is interpreted as an error message.
Indeed, if we strace it, we see:

Normal messages arrive with the “gmlo” prefix, but the “bind mounting”
message arrives with the “ptxc” prefix, which (guix store) interprets as
‘%stderr-error’ and raises an exception right away.
Not sure why we get that “ptxc” prefix.
