Comment:

 Assuming your diagnosis is right (it seems very plausible), the right
 thing seems to be that we should use un-buffered I/O only when doing truly
 interactive GHCi, and not when doing runghc, or ghc -e.

 So we've made that change, and will push the change into 6.6.

 Can you test a nightly-build snapshot to see if it fixes your problem?

 Meanwhile, we're closing the bug.  Thanks for reporting it

 Simon
