Is Docker Swarm Scheduler broken deliberately? (opens in new tab)

This seems like fairly boilerplate code to make sure you don't encounter conflicts in the scheduler across various goroutines.

I'm curious how long the wait was as it had to be pretty serious to explicitly make the code thread unsafe to "fix" it.

Mesos is written in C++. Mesos upstream is also looking to entirely remove the Zookeeper dependency so blind Java / JVM hatred is kind of stupid. Mesos is battle tested in multi thousand node clusters.
