It would be great that way but then the client changed the requirements
on us:

:p
If the collected data were TLS, then the dumping thread should be able
to ask each thread to provide data collected so far. That either
requires synchronization, which I did, which necessitated shared
Collector objects; or messaging, which would require each thread
checking their Concurrency message box.
I don't know...
A third option came to me: Each thread periodically puts their data to a
common location and dumper dumps whatever is aggregated up to that
point. This would reduce contention.
