Fix for large repos
Task	Implement bug fixes for very large repos
Owner	Bob Gobeille
Target	0.8.0

This task will implement the collection of bugfixes we’ve identified that prevent database timeouts and other issues with jobs not being run when the file repository grows extremely large (on the order of several Linux distros, or around 100+GB of stuff).

Note - this is a fix for a problem that most individual users will probably never see, but it’s important nonetheless
