When debugging a complex multi-process code like Rust compiler unit tests, the current `settings set target.process.follow-fork-mode child|parent` is too limiting because a compiler test does a tree-like traversal - forking a subprocess which may spawn another subprocess, waiting for the child to finish, and forking another process and waiting for that, etc. If the follow mode is `child`, it will stop debugging when the first child exits. If it is the `parent`, it will never go into any child processes.
Thus, it is currently impossible to add a breakpoint to the code and wait for it to be hit - because it might be in the second child process that runs.
Would it be possible for the debugger to re-attach to the parent process once the child exits?
