IMO... gross. We do pretty much this exact thing

Careful, these must cast to non-negative integers,

- probably the most radical solution is what i suggested, to
completely avoid the unique-mapping of file structures to an integer
range, and use the address of the file structure (and some cookies)
as an identification.
Careful, these must cast to non-negative integers, without

if you read my (radical) proposal, the identification is based on a kernel
pointer and a 256-bit random integer. So non-negative integers are not
needed. (file-IO system-calls would be modified to detect if 'Unix file
