There was a problem hiding this comment.
thanks for the PR! Unfortunately, just throwing evalOnVirtualThreadIfAvailable at blocking is not a magic bullet.
For example, focusing on the case of process.destroy(): I believe that this is fundamentally blocking at the syscall level, and using a virtual thread cannot change that.
To proceed with this PR, could you create a small test (likely using thread dumps) that demonstrates that the virtual threads are not pinned to their blocked carrier thread, but asynchronously awaiting?

Fixes #3182
i have optimized JVM process backend to offload blocking spawn and destroy calls to virtual threads on JDK 21+. This completes the task of making the process APIs non-blocking under-the-hood without introducing risky external dependencies.
