mh, that's indeed not nice.

Sorry, but a cronjob for this kind of things is not the proper solution.

Dear Maintainer,

I've been using cowbuilder a long time.  I recently noticed that I had
~20gigs of stuff in /var/cache/pbuilder/build:

 .../pbuilder/build $ ls -ld cow.[02-9]*
drwxr-xr-x 23 root root 4096 Dez 29 17:06 cow.21198

There were no active sessions, so it seems these are just forgotten
detritus.  I propose adding a cron job to clean those up.  I attached
one that works for me.
