Re: Linux file descriptor to InputStream

[cfowler <cfowler@outpostsentinel.com>]

The problem wht that is that it does not use the underlying posix
function to accomplish all tasks.  For example.  It does not use any
native code to access '/etc/passwd'.  IMHO the only code that should
access that file is code that is in libc.  In my case this would have
killed me.  Because I replaced all of the passwd() functions in glibc
with my own code to get passwords from a config binary structure. 
/etc/passwd does not exist so I would have gotten an exception.
