GetAvailableThreads

Note to Markus: I don't see any `GetAvailableThreads` in the gecko codebase at the moment.

Is [1] the right data ?

Summary: Expose the list of profileable threads through nsIProfiler → Expose the list of all threads which are available for profiling through nsIProfiler

Oh, wow, let me supply some context:

The profiler currently has a list of registered threads, in CorePS::RegisteredThreads. It could easily expose that list via a new nsIProfiler method, for example nsIProfiler.getAvailableThreads.

Severity: normal → N/A
Type: defect → task
Priority: -- → P2
See Also: → 1639791

This might be useful for about:processes to show an icon next to threads that are not registered.

And I was thinking about the reverse as well: about:profiling could also list the threads that are not registered, to both help Firefox devs to find more thread to register, and for users to know which threads may not (yet) appear in profiles.
