Hmmm....I added a -z flag over 15 years ago (to ignore failing syscalls).
I never saw it documented or in the help -- so I was about to redo my patch.

From Marty Leisner <leisner at rochester.rr.com>,
rewritten by mludvig:
* strace.c (not_failing_only): New.
(usage): Added -z switch description.
(main): Added -z switch parsing to not_failing_only variable.
* syscall.c (trace_syscall): Added not_failing_only handling.
I looked at the code and there's still something for -z there...
I just tried it and it still works.
I'm looking to extend it to you can filter out certain errno's -- i.e. in a
polling system, you can ignore EAGAIN and just look at real
output and real errors.
