Fiber::Profiler

Detects fibers that are stalling the event loop.

Motivation

Migrating existing applications to the event loop can be tricky. One of the most common issues is when a fiber is blocking the event loop. This can happen when a fiber is waiting on a blocking operation, such as a database query, or a network request, that could not take advantage of the event loop. This can cause the event loop to stall, and prevent other fibers from running. This gem provides a way to detect these fibers, and help you identify the cause of the stall.

Usage
