 If I open the same file twice with openFile, then close both handles, and
 then use writeFile to overwrite the file, I get a locked file error.

 I have attached a file which includes three test cases. One always fails,
 one always succeeds, and one sometimes fails when run multiple times, but
 only in GHCi.
