   wrongly only considers authentication if there's a user name provided.
   Bug report #1004841. How? http://curl.haxx.se/mail/lib-2004-08/0182.html
 
-* If you use a very large amount of file descriptors (more than FD_SETSIZE)
-  and then use libcurl, it might crash on its use of select() which then
-  stores data out of bounds. Bug report #948950.

 * --limit-rate using -d or -F does not work. This is because the limit logic
   is provided by the curl app in its read/write callbacks, and when doing
   -d/-F the callbacks aren't used! Bug report #921395.
