Comment (by stockrt):

 I am not sure if this initialisation of 'n_wrk_busy = 0' is required. I
 can see that in r4040 (post 2.0.4 release) when we declare a new stats
 variable, there is a field that seems to be the initial value. This does
 not exist for 2.0.4 release.

 So, this needs checks in my patches:

   VSL_stats->n_wrk_busy = 0;

 I also can see that sometimes variables are not initialised in 2.0.4
 release, but I prefer to publish my code the way I place it here,
 initialising this var. If you thing it is better not, please remove these
 extra lines.

 Regards,

 Rogério Schneider
