Hi,
I ran into the same problem you did, I thought it was something I
was doing wrong until I read your email...
Here is the fix I came up with.

+++ check_tcp.c Mon Feb 25 23:48:45 2008
@@ -82,6 +82,7 @@
if (fcntl(s, F_SETFL, O_NONBLOCK) == -1)
goto bad;
+ gettimeofday(&cte->table->conf.timeout, NULL);
bcopy(&cte->table->conf.timeout, &tv, sizeof(tv));
if (connect(s, (struct sockaddr *)&cte->host->conf.ss, len) == -1) {
if (errno != EINPROGRESS)
I should check for return codes on gettimeofday but here it is anyway...
I submited a bug report too.
