[Mono-list] ASP.NET on Mac OS X

The biggest problem is that the place the exception is thrown is in managed
code. System.IO doesn't natively provide support for the unique
identification of files, whether it be inode or whatever.

As a workaround, I patched the code to do the following.. (pseudo code)

if (web.config and Web.config exist)
    FileStream fs1 = File.OpenWrite(web.config)
        FileStream fs2 = File.OpenWrite(Web.config)
        return files_are_different;
    catch(Exception ex)
        return files_are_the_same;

This workaround should be a bit more robust and check the file contents as
well, as it is possible that an exclusive lock was placed on Web.config
before entering the inner try/catch.

I wasn't gonna submit the code as a patch because it is more of a workaround
than a 'perfect fix'.... but if someone wants the code, let me know.
