Description

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.

Fixed. The only workaround is not to have the file open more than once.

Thanks, this seems to have fixed the problem we were seeing in our real code. It may have also helped with some space usage as well. No good data on that though.
