Re: Test 1452 failing on ElectroBSD when executed with valgrind

Looks like to get anything useful from the telnet server log, you need
to specify --verbose there.

See curl/tests/negtelnetserver.py

Don't know if there's a default timeout on the socketserver object; you
can set timeout=None on it if so.

Beyond that, I'll let someone closer to the tests take over.

Good hunting.
