    One way to solve this problem was to index into the filedesc
    table and make out which files were open, save this information
    in some sort part of the process image, and then when the
Actually, that ties into the one open question for me:
Given the file descriptor table, how do I map files/vnodes back to
the absolute path of the file that they reference?
If anyone knows off hand how to do it, or that it can't be done,
please chime in. You'll save me at least an hour of mucking around.
    Anyway, this sounds ilke a really good idea!  :-)

Thanks.
