### Note about context-switch
To capture a thread context-switch event you need:
- On Windows: run profiling application "as administrator"
- On linux: you can run special `systemtap` script with root privileges as follow (example on Fedora):
```bash
#stap -o /tmp/cs_profiling_info.log scripts/context_switch_logger.stp name APPLICATION_NAME
```
APPLICATION_NAME - name of profiling application
