Instruments: How to trace stat() calls?

My iOS app is making too many calls to stat(), but I can’t find a good way to trace them with Instruments:

- The I/O Activity instrument, to my surprise, doesn’t show stat/lstat/fstat, although it does show most other filesystem calls.
- The File Activity instrument doesn’t work on iOS.
- The Instrument>Trace Symbol command doesn’t work on iOS.
- The System Calls instrument does show them, but not the path or the error status.

Any suggestions?

—Jens
