It seems like it'd be preferable to have an interface like:

     withMajorGCDisabled :: IO() -> IO()

or (for some definition of K):

     withMajorGCDisabled :: (K -> IO()) -> IO()

in order to ensure that it always gets turned back on eventually. Of 
course, the latter can be created from the former pair. It's just that 
the former reminds me a bit much of explicit memory management and how 
difficult it is to balance the free()s...

Live well,
