I found it leaking again and have restarted Apache. Further, I've
changed the cronjob which did a soft ('graceful') Apache restart every
half hour during US midday into a hard restart every hour (on the 34
minute mark) all day long.
This could cut off downloads, which kinda sucks.
Also, I've changed 'go' to avoid the fulltext search (on the title field
only, but still these often get stuck) if $wgDisableTextSearch is on.
