Caught autotest.py with these filehandles just hanging around.

This is probably something not doing an appropriate with statement....

Research direction
The bug report shows leaked file handles from autotest.py. Investigate the autotest code for places where file operations are not using context managers (with statements). Look for open() calls that lack a with block, especially in files related to build logs and replay operations. Check the Tools/autotest directory for the relevant scripts.
