I get two threads each time, one of which is probably never started and not
garbage collected due to a bug/feature of java jdk.
Such processes increment ThreadGroup.activeCount() but don't show up
when calling ThreadGroup.enumerate().
I have some 4000 such threads on a machine where only 80 are running.
Cause they are never started it is more a memory leak than a thread leak...
