BTW, if the answer to that involves turning the message back into an SV,
I think we should not do that but just use the SV that was passed in
originally.  Then the TRY/CATCH could go away entirely, ie the code
would become roughly like

    if (level < ERROR)
    {
        cmsg = sv2cstr(msg);
        elog(level, "%s", cmsg);
        pfree(cmsg);
    }
    else
    {
        croak-with-SV(msg);
    }

which knows slightly more about the meaning of "level" than before,
but otherwise seems much less entangled with anything.

It's still beyond my Perl-fu ...
