I fully agree that the memory manager for obvious reasons is an important subject, especially for heavily multithreaded code, and even more for any string stuff in such code. I haven't informed myself enough to judge how well the FPC memory manager behaves in this regard, and if it might make sense to try to use an alternative memory manager with FPC for Linux. However, being aware of that, we are avoiding reallocations wherever we can and instantiate pretty much every thing using own memory caches.
