Title:
  /etc/cron.daily/apt is holding memory while "sleep"

Status in APT:
  Fix Released
Status in apt package in Ubuntu:
  Confirmed

Bug description:
  The "random_sleep" function is calling "sleep". Thus the memory used
  by anacron, the /etc/cron.daily/apt script is frozen for minutes when
  the "random_sleep" blocks until the "sleep" program completes.

  Maybe an implementation of a delayed system call back would save
  memory. For example the script could register a call-back with "at"
  utility instead of using sleep.

  I think this problem is important, especially during a few minutes
  after the system startup. The desktop has to be responsive while many
  desktop tasks are temporarily using more memory for initialization
  during the first hour.
