Commit Message

Wrap lock around nailgun spawning to protect against worker threads racing to spawn servers

I'm working on parallelizing some jvm related tasks and I ran into the issue that if multiple threads running NailgunTasks attempt to call runjava around the same time, they may end up spawning multiple nailgun servers. This puts a lock around spawning them so that we can be sure they are only spawned once

Testing Done:
CI baking on PR, ran with parallel WIP and saw that no extra servers were spawned.
