There is a situation where process(PID).thread.begin probes will fire. - Start a process that creates several threads that will run for an extended period of time. Determine the pids of those threads. - RUn systemtap with a script that probes those pids. - As systemtap attaches to those threads, the process(PID).thread.begin probe will fire. In my opinion, changing the semantics here is too big/messy of a change. Instead, a new probe type, something like 'process(PATH/PID).thread.create', could be created. -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
