Comment 5 for bug 1183411

Further investigations:
- Ran strace on the apache PIDs, and looks like when apache is throttling up a lot, it is because it is serving files from the www/openembedded/sources/ directory, many times also the same file
- Running netstat, looks like when apache is swamped in that way, all the requests for files in www/openembedded/sources/ are coming from the same IP, using some sort of wget client
