#     Pull tracing fix from Steven Rostedt:
#      "Fix userstacktrace option for instances
#     
#       While writing an application that requires user stack trace option to
#       work in instances, I found that the instance option has a bug that
#       makes it a nop. The check for performing the user stack trace in an
#       instance, checks the top level options (not the instance options) to
#       determine if a user stack trace should be performed or not.
#     
#       This is not only incorrect, but also confusing for users. It confused
#       me for a bit!"
