commit d06aaaaf2bd8f3b5f0235e75f4f04c0ad69c7d6d

    ps: ignore SIGCONT

    SIGCONT is a continue signal. It seems that some zsh setups can send
    this signal, causing ps to abort. This is not what "continue" means.
    This change just uses the default handler which will continue a stopped
    process.
