Description: As reporter Oliver Thalmann (oliver.thalmann(a)chuv.ch)
pointed out, retrocl_init_trimming was repeating the retrocl_
housekeeping event every 5000 minutes instead of 5 minutes.
This patch fixes it to 5 minutes.

Thanks to Oliver Thalmann for his debugging.  As he figured out,
retrocl_init_trimming was passing the interval in microseconds not in
milliseconds.
