--- Comment #2 from Alan Somers <asomers at FreeBSD.org> ---
I figured it out.  The signal handler code is helpfully restarting the syscall
for me.  read(2) is actually returning to userland, but not to the stack from
whence I called it.  I need to use sigaction without SA_RESTART or siginterrupt
to fix it.  As is, auditd is using plain signal(), which automatically includes
SA_RESTART.
