What about extending the 'file' tool, which supports already 1, (2 combined with
3) and 4 ?
You have written (and I have checked this too) that 'file's execution time is
independend from the object file size, so this would speedup this detecion.
I've taken a look into the file source and have seen the only thing I don't know
is how to define a rule for a string with a variable fileoffset, because
'_dll_iname' is, as far as i can see, one of major identifier of import
For an example how to add support with fixed file offset
