Thanks for this pointer. Quoting from the report:
A semi-closed handle becomes closed:
* if hClose is applied to it;
* if an I/O error occurs when reading an item from the file item
from the stream;
* or once the entire contents of the file has been read.
What happens if one does NOT read the whole contents, but there are no
more references to the results of hGetContents? Is the file handle
closed anyway ? Here's an example of what I mean:
openFile n ReadMode >>= hGetContents >>= return . (take 10)
