| Can you tweak it a bit and see if it works even better if you put an
#if 0
| around the lines that read:
|
| +                               if (count > hz) {
| +                                       storming = 0;
| +                                       count = 0;
| +                               } else
| +                                       count++;

Removing these lines brings the storm down to ~978 per second, so yes,
this is better.  Thanks.

Joe
