    main: force enabling of I/O thread · 12d4536f

    Enabling the I/O thread by default seems like an important part of declaring
    1.0.  Besides allowing true SMP support with KVM, the I/O thread means that the
    TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which
    currently requires a (racey) signal based alarm system.
    I know there have been concerns about performance.  I think so far the ones that
    have come up (virtio-net) are most likely due to secondary reasons like
    decreased batching.
    I think we ought to force enabling I/O thread early in 1.0 development and
    commit to resolving any lingering issues.
