It wouldn't be a bad thing to at least try to start integrating as soon as possible, as it might affect the structure of what you are building...
Integrating as soon as possible is probably already going on. The DRLVM VM/GC interface has been basically stable for quite some time. If Xiao Feng finds a problem with VM/GC interface, we need to know about it immediately. Until then, GCV5 probably has little impact on the non-GC part of the VM. In other words, GCV5 already connects to DRLVM in much the same fashion as GCV4.x and MMTk. I think the question to ask Xiao Feng is when he thinks it makes sense for others to play with DRLVM/GCV5. It should be sooner rather than later.
From the above it looks like once the mature space collector is finished, we
can call for a vote to commit GCV5 to the repository. Once this happens, a standard build will produce GCV4, GCV4.1 and GCV5 DLLs. A command line switch will select between them. A command line switch for MMTk also needs to be added. Hopefully this will happen in the next month or so. geir
