There is a function user-real-uid that may be able to be extended to 
contain the full id. Currently it is documented as returning a float or 
int, neither of which will contain a SID without losing precision. We'd 
have to check the users first. If elisp had a bignum type, it would be 
the best choice, as a cons cell will require different code for 
processing it. But before embarking on this, I'd like to see a case that 
actually needs it, as there are many other areas where we could be 
spending our limited resources.
