This should fix it:
{{{

* make the hGetBuf/hPutBuf family work with non-FD Handles (#4144)
}}}
if it doesn't find an FD in the Handle, it uses the normal buffered
operations. Perhaps we could improve matters by allowing Handles to
optionally provide `RawIO`, but that's something for another day.
{{{
Prelude ByteStringHandle> bsHandle "test" "<fake file>" >>=
Data.ByteString.Char8.hGetContents
Loading package bytestring-0.9.1.7 ... linking ... done.
"test"
}}}
