* test-suite/tests/00-repl-server.test (call-with-repl-server): The REPL
server needs threads so don't bother testing if we have no threads.
Also, prevent SIGPIPE from killing the parent process.
Fixes <http://bugs.gnu.org/24769>.

* test-suite/tests/00-repl-server.test ("simple expression"): Add call
to 'select' before 'display'.
