Old issue was closed so I'm opening a new one.
#22807

Loading call stack and fetching local variables can be a long operations especially when there are a lot of threads started and call stacks are pretty long. Some debuggers (gdb for a example) allows you to do a step over before loading call stack or fetching local variables. Please allow debugger plugin to configure if it's ok to allow to step over before loading call stack and fetching variables.
