It may be as simple as changing APR_STATUS_IS_CHILD_NOTDONE, in
which case apr_proc_wait doesn't need to change at all. But i am
not sure that is the solution. No matter what, svn_io_run_cmd
will need to change so that it repeats the apr_proc_wait call as
necessary (unless you want to make apr_proc_wait itself loop over
waitpid(2), which i think is NOT the way to go).

Why not? Interrupted system calls are a very Unixy thing, and can't even
be simulated on Windows, for example. It's very unfriendly to have to
loop on something that's supposed to be a blocking call. I think the
Unix implementation should handle EINTR internally. That's the only way
to make the behaviour the same on all platforms.
