Hi Ken,

I have this very paper on my desk, printed out from (alas, much) earlier in the year. Anyone who has energy to address this would be very very welcome. Writing a concurrent incremental mark-sweep that handles ephemeron is the task. Making it function both in small bursts, e.g. after scavenging, and in its own thread is I think important; a non-threaded solution can be extremely efficient in certain contexts.

One experiment with multi-cores might be interesting -- concurrent GC.

The attached paper indicates an interesting strategy which worked OK for SML in terms of short pause times. Multiple cores could really reduce the total run (gc+mutate) time.

The basic strategy seems simple enough that it would not be tons of work to try out.

Not that I have much time either.. 8^(
