I tried both with this application.  Valgrind is considerably slower,
but works well enough for testing with just a handful of connections.
Running the daemon under gdb for a long time with lots of test clients
was what really nailed down the problem for me in the end, because it
was still fast enough to be usable, and when it aborted from the
assert I could look at a stack trace.
