Stacktrack is a profiling tool that records the peak stack usage observed for each thread in a process.
The Stacktrack VMO consists of a header followed by an array of nodes, indexed by zero-based integers. A linked list is built on top of this array, allowing a list of active threads to be maintained without requiring contiguous storage.
Each node represents a thread, storing the deepest stack trace observed so far. This structure allows a reader to reconstruct the state of all active threads simply by traversing the linked list from the header.
