[Haskell-cafe] Exclusive mode in openFile

It seems I'm not allowed to open same file both for writing and for reading:
Prelude System.IO> f_out <- openFile "mylog.log" AppendMode
Prelude System.IO> f_in <- openFile "mylog.log" ReadMode
*** Exception: mylog.log: openFile: resource busy (file is locked)
I use hslogger to write to logs, but I'd like to read parts of these logs *from
inside same Haskell application*.
How do I get around exclusive mode in openFile?
