I think this is working as designed. The default evaltime for dtrace is
postinit so it doesn't start tracing until after initializers have run.
Setting evaltime to exec will start tracing right after the process spawns so
will catch the initializers, but as Mark theorized this will break USDT probes
since they are setup in an initializer function.
