Release Display in *Pre-GC-Agenda* ?

[srt@CS.UCLA.EDU (Scott Turner)]

-------
If you are doing graphics on an Apollo from T, should you release the display
in the pre-gc agenda and then reacquire (the appropriate # of times) in the
post-gc agenda?  There is some claim that this doesn't work and/or screws up
the graphics.  Any truth to this?

What environment is *pre-gc-agenda* in?  What do the elements look like (i.e.,
are they argumentless lambdas)?  Can you code these as normal T, or do you have
to worry about interactions with the GC?

Anyone have the release/reacquire written for T3?  If so, could you send it to
me?
