using between 32-33GB of RAM after a 5 minute 4K sequential write test when using libc malloc. The good news is that it appears that crimson-osd is able to use tcmalloc for alienstore without significant modification. Better still, it drastically reduces memory usage. In the same test that...

Heap3 scheme only wraps the standard C library malloc() and free() functions to provide thread safety. In this case, when you use pvPortMalloc(), the function will use malloc() to allocate memory. It's not like vPortFree() isn't working. It is, but you will n...
