// The Gecko Profiler is an always-on profiler that takes fast and low overhead
// samples of the program execution using only userspace functionality for
// portability. The goal of this module is to provide performance data in a
// generic cross-platform way without requiring custom tools or kernel support.
//
// Samples are collected to form a timeline with optional timeline event
// (markers) used for filtering. The samples include both native stacks and
// platform-independent "label stack" frames.
