[Haskell-cafe] An interesting paper on VM-friendly GC

Somebody showed me this the other day, and I thought it was interesting:
Basically, "we designed a garbage collector which tries to avoid
touching memory pages that have been swapped out to disk just because we
need to do a GC sweep". Which is a pretty obvious thing to do, when you
think about it, and has several obvious performance implications. Maybe
we should think about how GHC handles this?
On the other hand, their implementation uses a modified Linux kernel,
and no sane person is going to recompile their OS kernel with a custom
patch just to run Haskell applications, so we can't do quite as well as
they did. But still, and interesting read...
