Hi all, I had this problem as well and applied the no-backfill patch from the Karmic ppa and it solved the delay problem. I started having the memory issues and thinking they were unrelated I participated in another bug <https://bugs.launchpad.net/ubuntu/+bug/432531> that should be marked as a duplicate of this one. I was running 64 bit at the time, but I get the same problems even after switching to 32 bit.
It discovered something that might help to track down the memory leak. I have ParaView compiled from source on my system (www.paraview.org, I compiled with MPI, Python scripting and the -j 2 option (http://paraview.org/Wiki/ParaView:Build_And_Install#Build_ParaView)) and if I start it and then quit it, even if I don't do anything at all in the program it clears a large portion of the leaked memory. It doesn't seem to clear all of it, but for sure about 800 MB can be reclaimed. I don't really know anything about video drivers and memory leaks, but hopefully this can help.
