+## Automatic housekeeping
+
+GitLab automatically runs `git gc` and `git repack` on repositories
+after Git pushes. If needed you can change how often this happens, or
+to turn it off, go to **Admin area > Settings**
+(`/admin/application_settings`).
+
+## Manual housekeeping
 
 The housekeeping function runs `git gc` ([man page][man]) on the current
 project Git repository.

 module Gitlab
   # This class implements an 'exclusive lease'. We call it a 'lease'
   # because it has a set expiry time. We call it 'exclusive' because only
   # one caller may obtain a lease for a given key at a time. The
   # implementation is intended to work across GitLab processes and across
-  # servers. It is a 'cheap' alternative to using SQL queries and updates:
+  # servers. It is a cheap alternative to using SQL queries and updates:
   # you do not need to change the SQL schema to start using
   # ExclusiveLease.
   #
-  # It is important to choose the timeout wisely. If the timeout is very
-  # high (1 hour) then the throughput of your operation gets very low (at
-  # most once an hour). If the timeout is lower than how long your
-  # operation may take then you cannot count on exclusivity. For example,
-  # if the timeout is 10 seconds and you do an operation which may take 20
-  # seconds then two overlapping operations may hold a lease for the same
-  # key at the same time.
-  #
-  # This class has no 'cancel' method. I originally decided against adding
-  # it because it would add complexity and a false sense of security. The
-  # complexity: instead of setting '1' we would have to set a UUID, and to
-  # delete it we would have to execute Lua on the Redis server to only
-  # delete the key if the value was our own UUID. Otherwise there is a
-  # chance that when you intend to cancel your lease you actually delete
-  # someone else's. The false sense of security: you cannot design your
-  # system to rely too much on the lease being cancelled after use because
-  # the calling (Ruby) process may crash or be killed. You _cannot_ count
-  # on begin/ensure blocks to cancel a lease, because the 'ensure' does
-  # not always run. Think of 'kill -9' from the Unicorn master for
-  # instance.
-  #
-  # If you find that leases are getting in your way, ask yourself: would
-  # it be enough to lower the lease timeout? Another thing that might be
-  # appropriate is to only use a lease for bulk/automated operations, and
-  # to ignore the lease when you get a single 'manual' user request (a
-  # button click).
