Matt Witherspoon fixed a problem case when the CPU load went to 100% when a
HTTP upload was disconnected: "What appears to be happening is that my system (Linux 2.6.17 and 2.6.13) is setting *only* POLLHUP on poll() when the conditions in my previous mail occur. As you can see, select.c:Curl_select() does not check for POLLHUP. So basically what was happening, is poll() was returning immediately (with POLLHUP set), but when Curl_select() looked at the bits, neither POLLERR or POLLOUT was set. This still caused Curl_readwrite() to be called, which quickly returned. Then the transfer() loop kept continuing at full speed forever."
