Comment (by dd32):

 So far all i've been able to determine is that yes, `random_int()` can be
 slow with OpenSSL on windows under certain situations in <= php 5.3.8.
 Using [https://en.wikipedia.org/wiki/XAMPP XAMPP] has shown that every
 call to `random_int()` takes roughly 1.2s using OpenSSL in those versions
 of PHP, which is about the same speed as PHP 5.3.0~5.3.3 in my testing.

 PHP 5.4.7 is orders of magnitude faster (The XAMPP version which includes
 5.4.4 is broken, and none include 5.4.0/5.4.1).

 I'm going to bump the WP version to PHP 5.4.1+ for OpenSSL since that's
 when the last major change occurred, and we can't really risk it.
