If you load it from within lldb via an LLDB command, does the problem still occur?  If the problem you are fixing is not specific to the LLDB command line, I would prefer if you write this not as a pexpect test.

I would love to not touch pexpect :-) But in this case, I can’t see a way around it. I am trying to detect whether some text is “physically” printed to stdout. And pexpect seems the most obvious straightforward way to get that to happen. Note that, in this bug, the result object is filled in correctly even if nothing gets printed, so looking at the result won’t quite cut it - it really needs to detect output to stdout

Do we support remote pexpect? As for FreeBSD and Linux, they might not be necessary, but I’d rather much remove them (or let the relevant platform owners) remove them in a separate commit
