lldb will only backtrace a fixed number of stack frames, as a last-ditch attempt to avoid a runaway looping backtrace. It's unusual that anyone ends up depending on this final safety net in years. I picked the original number of 300000 was picked by seeing how many stack frames I could make in a small recursive function on Darwin systems before using the default stack space. Checking again today on a modern system, I can exceed this limit & lldb will not show the original invocation of the recursing call. Double the old value to cover this larger maximum possible stack frame count, as a default value. (`target.process.thread.max-backtrace-depth`)
