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

[Rui Ueyama via Phabricator via llvm-commits]

ruiu added a comment.

Then why does it take so much time in some test cases if both are the same in the big-O? It should never create 65k+ threads. If it does, something's broken. This patch seems to be trying to fix at a wrong place.
