Comment (by Fábio Domingues):
One more detail. Using `objgraph.show_growth` without doing `gc.collect`
give us this on each new request:
{{{
list 1990 +10
dict 6798 +3
deque 20 +2
lock 43 +2
OrderedDict 11 +2
partial 24 +2
ReferenceType 3848 +1
DatabaseWrapper 6 +1
DatabaseClient 6 +1
DatabaseCreation 6 +1
DatabaseFeatures 6 +1
DatabaseIntrospection 6 +1
DatabaseOperations 6 +1
BaseDatabaseValidation 6 +1
DatabaseErrorWrapper 5 +1
PGconn 5 +1
Connection 5 +1
PrepareManager 5 +1
AdaptersMap 7 +1
TypesRegistry 7 +1
}}}
with the previous patch the output of `show_growth` is empty.
