[Ondřej Surý]

Control: fixed -1 php5/5.5.0~alpha1-1
Control: tags -1 wheezy

Hi Alexander,

you might want to pull cron job:
http://anonscm.debian.org/gitweb/?p=pkg-php/php.git;a=blob;f=debian/php5-common.php5.cron.d;h=8865fddb4c451f38f0d6f1ae722a3082c2eb5f81;hb=refs/heads/debian-experimental

and sessionclean script:
http://anonscm.debian.org/gitweb/?p=pkg-php/php.git;a=blob;f=debian/sessionclean;h=a5f5360d015a4e74199f8c71152ab96f0bd4bb33;hb=refs/heads/debian-experimental

I have already improved the session clean script, but it didn't make it
into wheezy, because of lack of testers with too many session files.

Unfortunatelly we cannot avoid looking at the files, because of #626640.
