This is not a bug but by design. In this case there are 8 separate threads
used for generating dot files or better said to start the dot program for
generating graph and the main program occupies 1 thread. The 8 dot threads
won't exhaust the processor as they do quite a bit of I/Oso the processes
will wait for this I/O. Attempt is to make optimal use of the available
(disc) resources.
