I don't know what system you are running on (is it windows), but the 
unix source code is a simple use of the access() system call and it's 
hard to see how that can go wrong (though I'm not sure what  
isReadableFileAtPath: *should* do ... for setuid programs ... check 
access for the real user id as it does now, or check access for the 
effective user id by using fstat or similar).  If it's windows, it may 
be that the call being used (GetFileAttributes) is not reliable for our 
purpose and we should be using some other call ... I don't know windows 
at all well.

Can you supply the source code for a testcase illustrating the problem 
so I can run it under debug and see what's happening?
