This problem is a bit specific to us, we have a huge ~6s overhead for launching processes. jsc-stress-tests takes over 24 hours to run due to each test launching its own process.
We would like a way to share a jsc process between tests.

The approach we were thinking of implementing was to use stdio on a shared process for tests. Because the test runner uses shell scripts and ruby, it doesn't seem possible on all platforms to send input to that process across multiple shell scripts.
We would likely need a way to use only ruby to run tests for this to work.
