Again, this leaves other users broken. Reproducer for QMP:
$ echo -e '{ "execute": "qmp_capabilities" }\n{ "execute": "query-name"
}\n[' | socat UNIX:/work/armbru/images/test-qmp STDIO
{"QMP": {"version": {"qemu": {"micro": 90, "minor": 12, "major": 2},
"package": "v3.0.0-rc1-21-g975ad3dcf2"}, "capabilities": ["oob"]}}
{"return": {}}
{"return": {}}
Note there's no error reported for the last line.
The simplification of the JSON parser I have in mind might make this
easy to fix properly. I'll look into it.
