Ah, very useful experiement and yes I agree it certainly seems like libcurl
doesn't tell you the correct action to monitor for, or possibly on the wrong
socket since it has two in the FTP case.

My initial guess is then that transfer.c:Curl_single_getsock() isn't good
enough for the FTP upload perform state...
