Normally, a panic/throw only shows the thread stack for the current thread and all paused goroutines. Goroutines running on other threads, or other threads running on their system stacks, are opaque. Change that when GODEBUG=crash, by passing a SIGQUIT around to all the threads when GODEBUG=crash. If this works out reasonably well, we might make the SIGQUIT relay part of the standard panic/throw death, perhaps eliding idle m's.
