Comment (by simonmar):

 The NCG has been leaking again, I just fixed it:

 {{{
 Fri Sep 11 16:28:12 BST 2009  Simon Marlow <marlowsd at gmail.com>
   * Fix a space leak in the native code gen (again)
 }}}

 This does reduce the peak memory usage for this test quite a lot, but
 we're still spending a lot of time in the NCG, and that needs
 investigating.  Space leak test added as `space_leaks/T3294`, so hopefully
 this won't re-occur.
