Are you sure about this? If you use working.directory="." then model file should be written in
current working directory and not in the temporary folder created by R.

I looked in ?tempdir() and there is no sign that we could modify permissions. I did not check the
permissions on linux, but I find it odd that 700 does not allow WinBUGS to open the file. Afterall,
700 should mean that all permissions are granted to the user (owner) of the file, which is the user
who started R and subsequently WinBUGS via wine.
