+- Revert Joshua Kwan's patch committed 11 Sep 2009.
+
+ Some systems poll function sets POLLHUP in revents without setting
+ POLLIN, and sets POLLERR without setting POLLIN and POLLOUT. In some
+ libcurl code execution paths this could trigger busy wait loops with
+ high CPU usage until a timeout condition aborted the loop.
+
+ The reverted patch addressed the above issue for a very specific case,
+ when awaiting c-ares to resolve. A libcurl-wide fix for Curl_poll now
+ superceeds this one.

- Joshua Kwan provided a patch to pass POLLERR / POLLHUP back to c-ares.
This fixes a loop problem with high CPU usage.
