How do I enable users to use dtrace on Mac OS X. I am trying to do the equivalent of strace on Linux, and I don't like running applications with elevated privileges.

UPDATE

Ok, the best I can tell. The only way to keep a nefarious application from ruining the system by debugging it is to.

1. Attach to the process in a separate console
2. Use sudo twice

So that:

sudo dtruss sudo -u myusername potentially_harmful_app

I verified this with this short program:

#include <iostream>
#include <unistd.h>
int main()
{
  std::cout << "effective euid " << geteuid() << "\n";
}
