asyncio in older Python 3.x (seen with 3.7) can seemingly hang if new_event_loop is called repeatedly in the same process. The reuse of processes in the Bitbake thread pool during parsing seems to be able to trigger this with the PR server export selftest. It appears that calling set_event_loop with the new loop avoids the issue, so that is now done in the asyncrpc Client initializer (with an explanatory comment). This should be revisited when the day arrives that Python 3.9 becomes the minimum required for BitBake. Additionally, it was discovered that using get_event_loop in the asyncrpc server initialization can trigger hangs in the hashserv unittests when the second test is run. To avoid this, switch to calling new_event_loop + set_event_loop in the initialization code there as well.

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: https://docs.yoctoproject.org
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
