[PD] [Gem]: gem-pointer and [list] OR slow [repeat]

it's a known trick to use [repeat] from zexy in a gem render chain to
produce funny effects and to multiply the rendering of the attached
the problem i have here, is that i use a [repeat] with a very high
iteration number (>1000). after the [repeat 1000] some stuff is
calculated and read from tables and then sent to gem-objects on each
iteration. this works well, but on each render-cycle i get a short
dropout. i use the default framerate of 20, that should make 50ms per
frame, but with [realtime] i measure around 70ms. i could live with
that, but i thought that this could be optimized.
it's the concept of pd, that when a message is triggered, it gets
completely processed in the same dsp-cycle. but when working with gem,
this makes absolutely no sense, since the time between each render cycle
is much higher (50ms in my case). that's why i wanted to build a slow
repeat with [until] and [list], so that i can spread the 1000 iterations
over the whole 50ms. unfortunately it is not possible to store a gem
pointer with [list]. when i connect a [gemhead] to the right inlet of a
[list] and turn rendering on, pd immediately crashes (at least here, i
didn't test on other computers).
i tried also to bang 'manually' the [gemhead] instead, but then the
iterations don't have any effect (no objects are multiplied).
is there any way to store a gem pointer? or is there another way of
producing slow repeats of a gem pointer?
any help appreciated!
