As discussed on irc this prevents fools like me from wreaking havoc
directly with the cli, at least if you still want to interactively
test stuff easily (background processes and all would work around
this). Imo it's better to disable (and maybe re-enable) the CRC stuff
when we disable/enable the pipe.
