[PD] Preventing pix_image to eat up all CPU

Has anybody ever used a considerable number of [pix_image] objects in 
the same patch?

If I do so, even if I don't load any image on any of them and even if 
they are all "disconnected" (meaning they are not receiving the 
gemlist), they eat up a lot of CPU. With 64 pix images doing nothing Pd 
is already eating up 75% of my dual core.

I wonder if anybody has run into the same issue, especially on Linux and 
found any workaround.

I'm completely stuck because I need to have a few images pre-loaded and 
at any moment, show one of them (and I can't dynamically load them with 
an "open" message on only one [pix_image], because loading is threaded). 
This shouldn't be cpu-consuming at all, as I'll always make only one 
image visible, but pix_image is consuming CPU merely for existing.
