+Daniel Stenberg (22 Mar 2010)
+- Thomas Lopatic fixed the alarm()-based DNS timeout:
+
+ Looking at the code of Curl_resolv_timeout() in hostip.c, I think that in
+ case of a timeout, the signal handler for SIGALRM never gets removed. I
+ think that in my case it gets executed at some point later on when execution
+ has long left Curl_resolv_timeout() or even the cURL library.
+
+ The code that is jumped to with siglongjmp() simply sets the error message
+ to "name lookup timed out" and then returns with CURLRESOLV_ERROR. I guess
+ that instead of simply returning without cleaning up, the code should have a
+ goto that jumps to the spot right after the call to Curl_resolv().
