> `libwinio_loop` must be initialized before `Socket` constructor is called

>                 URL: https://issues.apache.org/jira/browse/MESOS-9097
>             Project: Mesos
>          Issue Type: Bug
>    Affects Versions: 1.7.0
>         Environment: Windows with \{{-DENABLE_LIBWINIO=ON}}
>            Reporter: Andrew Schwartzmeyer
>            Assignee: Akash Gupta
>            Priority: Major
>              Labels: libprocess, windows
>
> When building with {{-DENABLE_LIBWINIO}}, initializing the Windows event loop 
> (specifically the pointer {{process::libwinio_loop}}) becomes a prerequisite 
> to creating a {{Socket}}. If it has not been initialized, then when the 
> {{Socket}} constructor calls {{prepare_async()}}, a null pointer is 
> dereferenced, leading to a hang on Windows.
> This was discovered in the simple program {{test-linkee}} where a {{Socket}} 
> is created and used, but the entire libprocess event loop is unused. This is 
> temporarily fixed by calling {{process::initialize()}} early in 
> {{test-linkee}}, but this should probably not be required. Instead, 
> {{prepare_async()}} (or any use of {{libwinio_loop}} should probably 
> auto-initialize the event loop if required.
> For now, I am adding fatal checks before a null pointer dereference.
