#202 chown failure

[Brian Tiffin]

::unicon
procedure main()
    # Change owner of file, usually only superusers can do this
    write(image(chown("chown.icn", "nobody", "nobody")))
end

causes a memory violation

::text
$ unicon -s chown.icn -x

Run-time error 302
File chown.icn; Line 12
memory violation
Traceback:
   main()
   chown("chown.icn","nobody","nobody") from line 12 in chown.icn

Thanks for the report. When someone made this thread-safe, they did not add the 2nd check for failure required by the new thread-safe function.
