[gambit-list] Garbage Collection BlackMagic

Maybe the right answer is "Don't do this in Gambit", but I'd like to give it
a try:

I'm writing an application, in Gambit. It does OpenGL graphics. It runs at
100fps. It's interpreted.

Now, put down the pitch fork -- the only thing it's doing at 100Hz is
  for 20 different objects
    glLoadIdentity
    glPushMatrix
    some rotation
    glCallList
    glPopMatrix

This works fine, _except_ when I get hit with a gambit gc, it costs me like
70ms ... which becomes a noticable lag in my otherwise smoothly rotationg
screen.

What are my options? Can I get a thread local heap? My basic usage is the
following:

launch gambit app
   --> it opens up a glut window
   --> it listens on port ABCDE for new graphics primitives

in my editor window, I type some code; I send new primitives to port ABCDE;
my gambit app spends a bit of time building it into a new display list

That's all. What can I do in this particular situation?

Thanks!
