Pavel Orehov reported memory problems with the multi interface in bug report #1098843. In short, a shared DNS cache was setup for a multi handle and when the shared cache was deleted before the individual easy handles, the latter cleanups caused read/writes to already freed memory.

curl_easy_perform_ev: debug/test function This function is meant to work *exactly* as curl_easy_perform() but will use the event-based libcurl API internally instead of curl_multi_perform(). To avoid relying on an actual event-based library and to not use non-portable functions (like epoll or similar), there's a rather inefficient emulation layer implemented on top of Curl_poll() instead. There's currently some convenience logging done in curl_easy_perform_ev which helps when tracking down problems. They may be suitable to remove or change once things seem to be fine enough. curl has a new --test-event option when built with debug enabled that then uses curl_easy_perform_ev() instead of curl_easy_perform(). If built without debug, using --test-event will only output a warning message. NOTE: curl_easy_perform_ev() is not part if the public API on purpose. It is only present in debug builds of libcurl and MUST NOT be considered stable even then. Use it for libcurl-testing purposes only. runtests.pl now features an -e command line option that makes it use --test-event for all curl command line tests. The man page is updated.
