The problem is that it is impossible to tell from the users p.o.v. whether svn
has hung (because of a bug) or hung (because svn is waiting indefinitely for
the server to respond and there are network errors).

A timeout would be useful here; if the client does not receive any response
from the server after x seconds (when expecting a response), report an error
and fail.

Looking at libsvn_ra_svn/marshal.c readbuf_input:

/* Always block for reading. */
  if (conn->sock && conn->block_handler)
    apr_socket_timeout_set(conn->sock, -1);

According to the documentation, apr_socket_timeout_set will:

        t < 0 -- read and write calls block

I'm not sure what block_handler does (or if it is set), but it might be worth
changing this.
