apache2 restarts

seems the (main) culprit is php session being built with mm:

built with mm:
# i=1;while true; do service httpd restart || break;i=$((i+1)); done; 
echo stopped at $i
Checking Apache 2.4 Web Server configuration.......................[ DONE ]

if built without mm, loop runs over a minute (i did hit ctrl+c)

with just these packages:

anyone misses if it gets in pld builds?
https://github.com/pld-linux/php/blob/auto/th/php53-5.3.29-14/php.spec#L45

it used to be disabled with php was built with zts
https://github.com/pld-linux/php/blob/auto/th/php53-5.3.29-14/php.spec#L88-L91

which was in 2010
https://github.com/pld-linux/php/commit/1f6a0184aaf7a90758fe809dd19c8471bdf43d36

mm itself was last updated in 2006
https://github.com/pld-linux/mm/commit/df219b969ed5f9d74fbe2b3c8382e5e5d2624253
http://www.ossp.org/pkg/lib/mm/

and php docs recommend using shm(tmpfs) instead
http://php.net/manual/en/session.requirements.php

and last, i don't even know how to use it! (=mm with session)  :)
some php.ini variable to enable?
