Bug #58217 Subsecond timeouts always fail

Description:
------------
Using floats for sub-second timeouts, which should be supported with my version of libcurl (7.16.3), doesn't appear to work.

Sample code below. 

Reproduce code:
---------------
<?php

$r = pecl_http_get('http://127.0.0.1', array('timeout' => 1.0));

$r = pecl_http_get('http://127.0.0.1',array('timeout' => 0.999));

?>

Expected result:
----------------
I would expect both calls to succeed - the local webserver is responding in less than 999 milliseconds.

Actual result:
--------------
The first call always succeeds, the second always fails (for any float value below 1) with:

Warning: http_get(): a timeout was reached; a timeout was reached (http://127.0.0.1/)

Reproduce code should be:

<?php

$r = http_get('http://127.0.0.1', array('timeout' => 1.0));

$r = http_get('http://127.0.0.1',array('timeout' => 0.999));

?>

What pecl_http version, and which libcurl version is exactly linked to php?

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Open". Thank you.

I am also experiencing this.

Curl version:
curl 7.17.1 (i386-apple-darwin9.0.0) libcurl/7.17.1 OpenSSL/0.9.7l zlib/1.2.3

Pecl_http version:
pecl_http 1.6.1   stable

Subsecond timeouts would be very helpful to have.

Thank you for taking the time to write to us, but this is not
a bug.

Sub-second timeouts needs libcurl built with (c-)ares support.
See http://curl.haxx.se/libcurl/c/curl_easy_setopt.html#CURLOPTTIMEOUTMS
