note 110923 deleted from function.curl-multi-exec by aharvey

Note Submitter: Anonymous ---- I think there's a bug in the sample code. If curl_multi_select() returns -1, the do..while loop just keeps calling it until it returns something else. So if repeated calles to curl_multi_select() can return -1 indefinitely (and the comments on the manual page for that function suggest it can), then the example code will just go into an infinite loop. I'd post a fixed version, but I'm not sure what a return value of -1 actually implies: Does it mean the entire multi-stack has failed somehow, or can we continue calling curl_mulit_exec()?
