| crtools || Non-stop memory (first?) pre-dump || medium || - || When reading only the memory we can avoid freezing tasks and draining memory with parasite. There's a system call named "read_process_vm" which can help us accessing the other task's memory. The disadvantage of this approach is the need for additional memory. We may control this behaviour by reading memory in chunks and not allocating to much of additional buffers.

| kernel/crtools || Speed up fetching info about tasks || medium || Andrey Vagin || Using proc to get info about tasks is nice but too slow. We have measured that having socket-based engine that would fetch info about tasks from the kernel speeds things up significantly. So Andrey is working on the [[Task-diag]] patchset that would implement that.
