    You can have multiple fd's open at the same time, which is a lot more
    convenient.

    I will _not_ add a fcntl-like or ioctl interface to this. They are ugly
    _and_ there are security issues (ie if you pass on the fd to somebody
    else, they must not be able to change the signal mask _you_ specified).

    One of the reasons for the "flags" field (which is not unused) was because
    I thought it might have extensions for things like alarms etc.
