Yup, one build cycle of `jam -aqj3 @alpha-raw` in r34965-gcc2hybrid was
enough to generate it. The uptime was between 20~30 minutes. I'll build
the image with just {{{
# define ENABLE_TRACING 1
# define MAX_TRACE_SIZE (300 * 1024 * 1024)
#define SYSCALL_TRACING_IGNORE_KTRACE_OUTPUT 1
#define VM_CACHE_TRACING 2
}}}
