system still gets stuck in Purgatory where there's little CPU activity but the disk goes like crazy. That's with R having almost the whole machine to itself and running a memory hungry compute only function. I've seen this behavior with other version numbers but I'm running R 2.0.0 under Fedora Core 3. The system is a laptop with 1 Gig. RAM.
I don't see it on machines with 1 or 2Gb of RAM and 3-10Gb of swap.
