[PD] pix_multiblob cpu usage

[nosehair911 at bellsouth.net]

I tried to use the Gem from the latest pd extended autobuilds and I have also compiled my own from 
CVS with the same results.  If you can point me in the right direction on how to get this going I would 
apreciate it.  BTW I dont know any C or C+ but I am willing to give it a go.
Thanks,
Alain
