I think this behavior is caused by (or at least related to) the
following GHC bug:

http://hackage.haskell.org/trac/ghc/ticket/2363

That bug has been fixed for the 6.10 release; my testing indicated
that your program behaves correctly in that version.  See the above
bug report for some suggestions on how to work around the 6.8 getChar
blocking.

Hope that helps,
