mgronlun left a comment: | am approving this PR for the following reasons: 1. We have reached a state that is "good enough" - | no longer see any fundamental design issues that can not be handled by follow-up bug fixes. 2. There are still many vague aspects included with this PR, as many has already pointed out, mostly related to the memory model and thread interactions - all those can, and should, be clarified, explained and exacted post-integration. 3. The feature as a whole is experimental and turned off by default. 4. Today is the penultimate day before JDK 25 cutoff. To give the feature a fair chance for making JDK25, it needs approval now. Thanks a lot Johannes and all involved for your hard work getting this feature ready. Many thanks Markus
