Steps to reproduce the problem:
1. Use chromebook with android apps without reboot
2. 
3. 

What is the expected behavior?
Performance does not degrade over time, linux open files are closed

What went wrong?
System is sluggish, some crouton apps do not open due to "too many open files"
lsof reports almost 1 million open files

See attached lsof (~100MB when unpacked) files are reported not found since it is a chroot

Did this work before? N/A
