Well... ghc still has a single-threaded garbage collector, so all the

A real time incremental gc would be really cool. Some people claim
they exist, but which languages have one?
james mccartney's supercollider [1] has a non-copying incremental
collector based on [2], though not a parallel one.
btw, is an implementation of the incremental collector described in
[3] available somewhere? are there any plans to incorporate it into
future ghc versions?
