[PATCH] D36607: [Support/Parallel] - Do not spawn thread for single/last task.

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

It is broken. The taskgroup should not spawn more threads than the number of physical cores however it is used. It is intended to be a thread-pool, and spawning threads per task is nonsense.
