  • Version: v8.9.3 / any
  • Platform: Windows 8.1 x64 / any
  • Subsystem: debugger API

Consider the case when some library created a long setTimeout or any setInterval and didn't cancel it when finished some main action. There should be a tab in Inspector (and corresponding debugger API) to show the list of pending asynchronous computations, so that it's clear why Node.js process is unable to shut down.

Technically speaking the requested information is already exposed via process._getActiveHandles(), the missing part is probably a new domain in the inspector protocol that integrate this information.

Note that with #14901 and nodejs/llnode#122 it's possible to get that information from a core dump or a running process attached by lldb.
