From 3f40a2efe835ba6c6660485f11d0460332d401d1 Mon Sep 17 00:00:00 2001 From: Chris Larson Date: Thu, 23 Sep 2010 11:21:29 -0700 Subject: Reduce bb.cache memory usage a bit - Don't store key/value pairs when the value is None - Delete the depends_cache when we're done with it This reduces the memory usage after sync on initial parse by roughly 11.5% on this machine.
