Not an infinite loop, intensive (and almost hopeless) garbage collection. You're operating in huge dimension and very small space, so that 99.99% of the running time is spent in desperation GC. I have reduced memory use for such very sparse matrices, so the above is fixed. But the same phenomenon is likely to occur again, in larger dimensions.
