Therefore my question should be restated as:
Would perf developers accept the "syscall pausing" feature,
or it won't be accepted?
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.
