Comment:

 I'm wontfixing my own ticket; since CACHE_BACKEND allows extension, this
 doesn't belong in core.

 I'll see about adding this to django-extensions.

Comment:

 I can see that there is room for a dogpiling and other cache management
 strategies. However, as jdunck notes, this can now be acheived with a
 custom cache backend. This patch would need to be recast in those terms if
 it were to be integrated into trunk.

 Regardless, this won't be happening for v1.1

Comment (by jdunck):

 krystal, in fact this is an improved version of that snippet.

 However, I would be surprised if this was included in core-- it can now be
 accomplished with a custom CACHE_BACKEND.

Comment:

 FYI, there is an other snippets that do the same :
 http://www.djangosnippets.org/snippets/793/


 IMHO, this change should really be merged in the core ; dog-piling is a
 common and dirty problem for everyone who have a few visitors and it's not
 adressed in django.

 If the patch is not included, we should mention this effect on the
 Documentation page to help people know why their server crash under load
 :)

 (I put the milestone to 1.1 so this patch get a "design decision", sorry
 if I shouldn't)
