State of parallel GC?

[Jeremy Shaw]

Hello,

Is real-time, parallel garbage collection at all feasible? 

My thinking is, real-time garbage collection requires the garbage
collector to be able to work on the problem in small, predictable,
pieces. That seems like something which would also be useful for
scaling up GC to multiple cores? 

I am curious, because I have a project in mind that would benefit
greatly from real-time, parallel garbage collection :)
