Graham, i have run your test program, both with and without fork(), against phkmalloc from 2.2 upgraded to CTM 470 for over 10 million iterations. the upgrade replaces /home/src/lib/libc/stdlib/malloc.c version 1.18.2.2 with version 1.18.2.3. there are changes in the way that phkmalloc deals with changing sizes fo allocated memory and more. ;) can you upgrade from 2.2.2 to 2.2.5 and run your code again? 2.2.5 will be out very soon. the source tree will be tagged within the hour (Oct 20th 6pm PDT). jmb
