[Bug]: Question: Are cores from `IBuildEngine9.RequestCores` expected to be released between batched task invocations?

[radical]

Issue Description

EmitBundleBase task in dotnet/runtime uses IBuildEngine9.RequestCores, and depends on these being released when the task's Execute is done. But if the task is batched, then for any subsequent invocations the task gets blocked on RequestCores. If I use ReleaseCores before returning from Execute, then it works fine.

Is this the expected behavior?

Steps to Reproduce

Your task should release cores, but also yes, each batch should release any unreleased cores from that task invocation.

Ok, so release as soon as that parallel work is done 👍

We are considering changes so it will release cores after each Execute.
