This idea (using ra_local from another process) has tremendous merit,
IMO. When ra_pipe is complete, we could do exactly that (and without
relying on sockets, shared-memory, message-passing, etc).

Right now, the pipe is established via something like:

char *argv[] = {
    "/usr/local/bin/ssh",
    "user@host",
    "svnpipe",
    NULL
}

svn_pipe_t *pipe;

SVN_ERR(svn_pipe_open(&pipe, argv, pool));

If we were to simply do

char *argv[] = {
    "/usr/local/bin/svnpipe",
    NULL
}

instead, then things should work fine; the SIGINT would not be
delivered to the child process.
