Description
Profiler options (at least -o and -t) are "persisted" between profiler runs (pairs of attach-stop). As a result, one can not disable them once they have been set.

Steps to reproduce

0. Start or restart a Java process that will be profiled.
1. Run profiler.sh -d 5 -f prof.txt -o summary,traces=1 -t 1234.
2. Try turning off -t option and disable traces: profiler.sh -d 5 -f prof.txt -o summary 1234.
3. Observe that profiler's output still works as if options traces=1 -t have been set.

Workaround
Restart the Java process that is being profiled. This means that the profiler options are either stored in the memory of the process, or in a temporary file that is deleted once the process quits.
