Hi,

 I have found a way to 'hang' a DLL created using ghc-6.5.20061006 under
 Win32. This occurs when I dynamically load DLL built using GHC, call one
 of its exported functions that uses file IO and then exit my program
 without explicitly releasing the DLL first. I have uploaded a test
 application to http://eeter.fi.tartu.ee/~mark/ghc_hang.zip that
 demonstrates this issue.

 I am not sure if I can call this a bug, as when I unload the DLL,
 everything works fine. But this does not happen in GHC-6.4.2 or older
 versions.

 Regards,
 Mark
