[Haskell-cafe] In-memory Handle for testing

[Simon Hengel]

For testing I want to stub handles, performing all reads and writes in
memory (and in process, so no mmap).  From looking at the documentation
of mkFileHandle[1], I think this should be possible.  But it requires
some work.  Is there already something out there?

Cheers,
Simon
