[New-bugs-announce] [issue35370] Provide API to set the tracing function to be used for running threads.

[Fabio Zadrozny]

New submission from Fabio Zadrozny <fabioz at users.sourceforge.net>:

Right now it's hard for debuggers to set the tracing function to be used for running threads.

This would be really handy for debuggers when attaching to a running program to debug all threads.

-- Note: currently there is a way to achieve that by pausing all the threads then selectively switching to a thread to make it current and setting the tracing function using the C-API (see: https://github.com/fabioz/PyDev.Debugger/blob/master/pydevd_attach_to_process/dll/attach.cpp#L1224), but I believe this is very hacky and not portable to other Python implementations.
