 > cURL internally rounds this up if necessary

 In the past (6-7 years ago), we found that not to always be the case.
 While I have not done any tests recently or tested all known versions of
 libcurl, it has been shown that giving too low of a timeout to a call to
 curl will result in curl simply not making the resulting web request at
 all.

 Basically, if you send at least some versions of curl a timeout value
 lower than 1 second, then the HTTP GET request never actually happens. It
 doesn't "timeout", because it never actually times in to start with. It
 simply returns, having done nothing whatsoever.
