No, no features will be back ported to PHP 4.4.
Although I dont see this as feature more like a fix (uneeded opens() stats() on each call) still thank you for the fast reply.
p.s. lately the topics and discussions on internal list are pretty scarry.. starting with political issues and ending with memory manager flaws (besides also some phparchitect articles which propose/show 5.2 being faster in all generic tests still slower in realworld aplications).. which probably makes a lot (at least me) users uneasy about switching to the 5.2.x tree :)
