- Each thread has a local buffer to store IPs during the uninterruptible stack walk.
- After period the recorder thread will copy the content of local buffers in global memory uninterruptibly with acquired thread lock.
- After the copy phase, the recorder thread will read the data from the global buffer i.e. IPs, and iterate the stacks.
