Returns an estimate of the number of active groups in this
thread group and its subgroups. Recursively iterates over
all subgroups in this thread group.
<p> The value returned is only an estimate because the number of
thread groups may change dynamically while this method traverses
internal data structures. This method is intended primarily for
debugging and monitoring purposes.
@return the number of active thread groups with this thread group as
an ancestor
