Threadpool for logging instrumentation terminates before we finish logging on crashing traces

[ftc]

If we have a callback that is called synchronously within a callin that throws an exception then the threadpool is shut down too soon resulting in a further logging of an exception exit to cause a threadpool error.

Trace

This is currently not a major issue as we are only verifying non crashing traces but it should be fixed at some point.
