Kristian Rosenvold updated SUREFIRE-947:
----------------------------------------
Description: I am running on a multicore machine with
{{forkMode="perthread"}} + {{threadCount="1"}} + {{reuseForks="true"}} and not
seeing any parallelismââ¬âat least {{jps -lm}} reports only one
{{surefirebooter.jar}} process. {{perCoreThreadCount}} defaults to {{true}} so
I expected to see 4 (or 8?) processes. Seems that I have to explicitly specify
a larger {{threadCount}} in order to get actual parallelism. (was: I am
