I have been using perf-trace a lot lately specifically because it is 
effectively a 'passive' observer of the task (e.g., time-sensitive tasks 
can be traced with perf but not with strace).

Also, your solution would not work if the raw_syscall events are written 
to a file for later analysis where as using tracepoints to collect this 
information would.
