I think some (most?) ferrites have a maximum permissible flux level.  
Driving them above that causes them to be, well, "less ferriteish".  I 
wonder if this large gap current will deferrite the ferrites?

This sounds similar to various magnetic amplifier delay inductor schemes, 
often times to allow for a slow initial current turn-on for an SCR ( to get 
the whole die turned on) before the main inrush...

Interesting work, guys!
