Comment(by simonmar):
The real problem seems to be that we're using `_open` from the CRT, which
returns `EACCESS` when opening a directory. In fact, `System.IO.openFile`
is behaving incorrectly on Windows when asked to open a file.
If we used the proper Win32 API we'd be able to handle this more cleanly,
but that requires a rewrite of the IO layer on Windows.
I'm ok with the proposed patch as a temporary workaround.
