When parsing recipes its apparent the memory usage of bitbake rises linearly with number of recipes parsed. It shouldn't. Using tracemalloc (thanks for the tip Joshua Lock) it was clear that the dependency information left behind in siggen was the culprit. Add a new method to allow us to drop this information. We don't need it after the recipe has been parsed and hashes calculated (at runtime its different but only the currently executing task would be in memory). This should give signficant memory usage improvements for bitbake and that in turn should help speed on more constrained systems, as well as when used in multiconfig environments.

Bitbake
BitBake is a generic task execution engine that allows shell and Python tasks to be run efficiently and in parallel while working within complex inter-task dependency constraints. One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software stacks using a task-oriented approach.
For information about Bitbake, see the OpenEmbedded website: http://www.openembedded.org/
Bitbake plain documentation can be found under the doc directory or its integrated html version at the Yocto Project website: http://yoctoproject.org/documentation
Contributing
Please refer to http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded for guidelines on how to submit patches, just note that the latter documentation is intended for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org) but in general main guidelines apply. Once the commit(s) have been created, the way to send the patch is through git-send-email. For example, to send the last commit (HEAD) on current branch, type:
git send-email -M -1 --to bitbake-devel@lists.openembedded.org
