> All the methods in ReporterManager are synchronized, effectively making this
> whole subsystem a blocker in terms of performance. Single threaded providers
> wast time acquiring the lock, parallel providers have a choke point blocking
> parallelism. Since this block guards all the file writing of reports, it
> effectively reduces performance quite a lot.
