>I wonder what the circumvention is for uninitialized memory, which is important for large data structures in high performance code. Actually there's not really much of a means around this. You could use static memory, which is only initialized once, and you can mmap pages directly from the kernel without initializing them, but allocating uninitialized data on the stack is not possible afaik.
