Socket handle leak and active handle warning with Vibe-D

[Selim Ozel]

I created the simplest possible example as explained by the 
Vibe-D community in [1]. The exact source code of what I run is 
in [2].

On Windows I get a socket handle leak warning on shutdown with 
crtl+c from terminal after running the executable.

> Warning: 2 socket handles leaked at driver^ Cshutdown

On Ubuntu 20.04 I get leaking drivers warning with the same 
process.

I really don't know what this is all about but it is at the core 
of my Vibe-D development. So any pointers you might have would be 
very helpful to me.

Thanks in advance.
