`Log.CloseAndFlush()` deadlock on AWS Lambda

See original GitHub issue

Log.CloseAndFlush() seems to be deadlocking when run in AWS Lambda and my Seq server instance goes down for some (irrelevant) reason making Seq a single point of failure for the whole microservice gang. This is how it looks like in the logs:

LoggerTimeout

This only happens when running in AWS Lambda environment. In a console app execution continues after a graceful timeout of ~4 seconds. I suspect it might be related to this and followed this advice to make it behave better:

...
finally
{
    Task.Run(Log.CloseAndFlush).Wait(1000);
}

It works but still looks like a hack.
