Nor here on my ICH8-based notebook, with 2GiB RAM. If anything, 3.2 seems worse than 3.1 when it comes to the ability of one process to binge out on dirtying pages, and then bring the rest of the system down to a snail's pace.
One consistent example case is unpacking to the local SATA drive an ISO image (using Nautilus, for example) stored on another drive. Compute-heavy processes with little disc access suffer (and even those without any I/O do --- CPU usage shoots right down).
Another one is a kernel build. The file cache goes bananas, and even with no other desktop applications loaded, everything gets paged out and it takes around a minute (in the worst case) for the unlock screen prompt to appear.
