I swear I already did this somewhere but it got lost, this adds additional thread pool stats exposed in .NET Core 3.1+. We'll get for example ThreadPool.PendingWorkItemCount on exception messages to better indicate app contention.

I'm not a big fan of how existing works - was light touch, let's get existing PRs touching it in, then I'll add a bench and do a builder pass and such on the exception path, no reason we can't be civilized with the GC!

@mgravell allocated in the exception path - I don't think it's a major item but would like to go through and end-to-end builder these paths once existing PRs are in (several touch it). |
