[OpenSCAD] Problem with complex scad file

I had the same problem as you, when opening y-carriage2.scad
I ran 'top' to learn more: openscad uses 99% CPU for a few seconds,
then after printing "CSG Normalization" it rapidly gobbles up 800 M
RES and 990 M VIRT memory, and SWAP climbs into the high 70s M. Cpu
drops to about 5-10%.
I am running ubuntu 10 with 1 GB ram, openscad 2011.10.15
To run openscad without completely hard-locking my system I use ionice
+ nice, for example:
ionice -c 3 nice -n 19 openscad y-carriage2.scad
I am not sure of a workaround, other than breaking the part up into
smaller pieces... sorry
