--- Comment #3 from Alan Somers <asomers at FreeBSD.org> ---
cap_rights_limit must've exited 0, because otherwise dd would've aborted.  I
don't know about truss, but I tried both ktrace and dtrace.  Dtracing
syscalls::cap_rights_limit:enter showed the same value for the capabilities in
both 64 and 32 bit mode.

Why do you say that cap_rights_limit has no 32-bit version?  I see it in line
1033 of sys/compat/freebsd32/syscalls.master.
