It would be nice to do it in the filter code.  The coefficents parameter  
is a parameter of the filter after all, and the use of the delay can be  
looked at as an implementation detail.  If the filter constructor (body)  
could access the delay buffer, then the delay buffer could expose a method  
to allow resizing.  Is that possible?
