Content
This is a very interesting patch, thank you. I've tested it on Mandriva 64-bit and it indeed fixes the free() issue on the XML workload. I see no regression on pybench, stringbench or json/pickle benchmarks. I guess the final patch will have to guard the mallopt() call with some #ifdef? (also, I suppose a portable solution would have to call mmap() ourselves for allocation of arenas, but that would probably be a bit more involved)
