There's a new version of the patch available at: http://www.canonware.com/~jasone/jemalloc/jemalloc_20051202b.diff This version of the patch adds the following: * Prefer to use sbrk() rather than mmap() for the 32-bit platforms. * Lazily create arenas, so that single-threaded applications don't dedicate space to arenas they never use. * Add the '*' and '/' MALLOC_OPTIONS flags, which allow control over the number of arenas. As of this patch, all of the issues that were brought to my attention have been addressed. This is a good time for additional review and serious benchmarking.
