    Have a look at:
    http://www.scs.ch/~frey/linux/kernelthreads.html
    I have an example there that starts and stops kernel threads
    from init_module and never produced a zombie.
    I use the same code also to start threads from ioctl and it
    works for me. I tested it on UP and SMP, Intel and Alpha,
    2.2.18 and 2.4.2.

    Regards,

    Martin
