Benjamin Mahler commented on MESOS-3941:
----------------------------------------
[~tnachen] can you elaborate? The example in this ticket is referring to
incorrect usage of {{async}}. In particular, we need to eliminate blocking
functions like {{net::contentLength}} in favor of a non-blocking version.
> Using 'async' to invoke blocking functions will block work threads.

> Key: MESOS-3941
> URL: https://issues.apache.org/jira/browse/MESOS-3941
> Project: Mesos
> Issue Type: Bug
> Reporter: Jie Yu
>
> Saw a few occurrences in the code base. For instance:
> https://github.com/apache/mesos/blob/master/src/slave/containerizer/fetcher.cpp#L382
> The current implementation of 'async' will create a libprocess process. That
> means if the function is blocking, a worker thread will be blocked. If we
> have too many such instances, we might end up deadlocking.
