From 0b9caf9b3166c8deb3c4f3a774c2384b069dc29c Mon Sep 17 00:00:00 2001 From: Fam Zheng Date: Tue, 26 Aug 2014 15:15:43 +0800 Subject: coroutine: Drop co_sleep_ns block_job_sleep_ns is the only user. Since we are moving towards AioContext aware code, it's better to use the explicit version and drop the old one.
