[PD] avoiding collapse of freeverb

Any digital filter will "blow up" when it becomes saturated. Clipping to 
-1 and 1 doesn't help, because then you could be sending values of -1 
and 1 almost constantly to the object. Look at the help file for 
[limiter~] and use that ahead of your freeverb perhaps. Not having a 
high value for the feedback in the reverb itself can help.

"nan" stands for Not A Number, and objects give this when they are 
incapable of calculating values any more.
