ODE (Safe handle has been closed) after IApplicationLifetime.ApplicationStopping callback is called on HttpSysServer

[avparuch]

Describe the bug

An object disposed exception is thrown after executing IApplicationLifetime.ApplicationStopping's registered callback on HttpSysServer

To Reproduce

This appears to be race condition during application shutdown, I'm not able to provide a minimal/consistent repro at this point. Will update the issue if I can find a consistent repro.

Exceptions (if any)

ProcessRequestAsync
