I used to do this a lot with my EDPs.  Worked fine for me!  I did an "I Am
Standing in a Room" treatment of a Brown and Williamson Tobacco answering
machine message for the chain tape project.    I called it "I Am Smoking 
in a
Room".  :)  The feedback path went through an SPX-90.

The feedpath path levels are quite touchy.  I had to constantly tweak 
levels.  I
wanted to use this technique in a live performance but it always seemed TOO
touchy.  I like your term "meltdown".  With my Kyma, I can do the entire 
thing
digitally with enough control.  I imagine the MAX/MSP folks could do 
likewise.

If this is what you're hearing, it's not signal path stuff.  Could be a
grounding issue.
