Bug#580971: apache2: htcacheclean not stopped by init script

[Frederik Himpe <fhimpe@vub.ac.be>]

Package: apache2
Severity: normal

When stopping apache2 using its init script, the running htcacheclean
process is not stopped. When restarting apache2 multipe times, this
results in many htcacheclean processes running at the same time.
