[Mono-dev] Loader Optimization with mono

AFAIR, multiple app-domains share things inside the same process.
It's like, for example, in ASP.NET where there are multiple web sites
running in the same web server (thus a single mono/.NET VM instance). If
you use web farming, or as is typical in ASP.NET Core start separate VMs
for each web app, there won't have any sharing of jitted code.
WIth multiple AppDomains in the same process, common code will be jitted
once and shared by all the applications, but beware that different versions
of core libraries will jit to different executable code, meaning possible
duplication of generated code.
As far as you spin multiple VMs these don't share code, for many reasons,
security ones being the top ranked.
