Handle batched commands with python API
Putting in commands with multiple parts (eg. foo.cmd('aa; axt foo')) desyncs at least the python API, as r2 sends a NULL as each command finishes, and r2pipe only expects one and stops reading there. Can we handle this or put a note somewhere obvious?
That depends on the channel . With spawn is like this but will work on http and maybe in pipe mode too

running ‘aa’ is not recommended, but this could be the reason why in some cases aa/aaa unsyncs the r2pipe communication

Actually, I was able to replicate it with any command with a semicolon, the
aa was just an example. This was specifically on the python backend using
e.g. r2pipe.open("/bin/ls") (can't remember which backend that is).

so the \0 terminator should be stripped down until the command ends, this can reuse the mutex logic to avoid printing that
but from your test i cant reproduce the issue, which OS are you running this?
also which version of r2
