Changes (by brianh at metamilk.com):

  * severity:  normal => major

Comment:

 I've changed the severity to major because I feel this bug prevents me
 distributing any binaries compiled under ghc6.6 for Windows, since whether
 or not the bug is "visible" (ie if you choose to run the binary under a
 debugger), obviously something is very wrong indeed with the runtime or
 else it wouldn't be trying to use an invalid handle (or cause one of the
 windows DLLs to do so) at program exit.
