                     11:   * Based on example code (c) 1988 The Software Distillery
                     12:   * and published in Transactor for the Amiga, Volume 2, Issues 2-5.
                     13:   * (May - August 1989)
                     14:   *
                     15:   * Known limitations:
                     16:   * Does not support ACTION_INHIBIT (big deal).
1.1.1.6   root       17:   * Does not support several 2.0+ packet types.
1.1       root       18:   * Does not support removable volumes.
                     19:   * May not return the correct error code in some cases.
                     20:   * Does not check for sane values passed by AmigaDOS.  May crash the emulation
                     21:   * if passed garbage values.
1.1.1.3   root       22:   * Could do tighter checks on malloc return values.
                     23:   * Will probably fail spectacularly in some cases if the filesystem is
                     24:   * modified at the same time by another process while UAE is running.
