Elderly BSD-ish systems (at least, I assume Darwin is relatively elderly, the man page is dated 2008) don't support piping or even renaming core files (according to the man page). I stand by my original suggestion: documenting the ulimit command takes up only one line, and may be useful to many users if their crash is easily reproducible -- even if they don't know how to do that yet, they're likely to accidentally trigger it again in the process of attempting to complete the work interrupted by the first crash.
