 I've installed 4.4.1 and 3.7.

 When I run a simple loop to that runs wp_insert_post,

 The memory usage increases as the loop progresses in 4.4.1, whereas in 3.7
 it stays the same.

 This eventually leads to an out of memory error in 4.4.1. I believe this
 is a regression introduced in the 4.X version as it has always worked
 before.

 To see this just add on each loop:

 echo memory_get_usage()/1024.0 . " kb \n";

 If you need to me write up some test code you can just add quickly to
 verify let me know. I will take a look through the wp_insert_code as well
 to see if I can find where the issue is myself. I've also tried the
 wp_suspend_cache_addition(true); as well as define( 'SAVEQUERIES', false
 ); But those do not effect the memory consumption. In any case, it still
 works fine in 3.X so I assume something changed.
