Alas, I get the error, openBinaryFile: resource busy (file is locked).

What is the proper work around for this?

This behaviour is specified in the Haskell standard. I don't know what the rationale is intended to be, but I don't like the behaviour either.

I believe you can work around it by using System.Posix.IO to open a file, then convert the Fd to a Handle.
