Of course, using just -p PID without any probes will result in dtrace hanging with nothing to do, but it will no longer exit nor cause the underlying process to exit. http://svn.freebsd.org/changeset/base/234234 Responsible-Changed-From-To: freebsd-bugs->gnn Responsible-Changed-By: gnn Responsible-Changed-When: Fri Apr 13 20:24:35 UTC 2012 Responsible-Changed-Why: The latest fixes to user tracing in DTrace will cure this problem.
