Public bug reported:
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.
