Repeated reopening and closing large projects was causing heap thrashing due to paging stuff in and out of JGit's internal window cache. This problem persisted even when preopening the repos to get them in JGit's internal RepositoryCache. We can simplify the code and avoid heap thrashing by just rebuilding one project at a time in each thread. This way we can also reuse a single NoteDbUpdateManager to make the ref update batching behavior more transparent. This does not completely eliminate performance issues, particularly on spinning disk, but as I write this I am rebuilding AOSP with no particular CPU thrashing issues.

Gerrit Code Review
Gerrit is a code review and project management tool for Git based projects.
Objective
Gerrit makes reviews easier by showing changes in a side-by-side display, and allowing inline comments to be added by any reviewer.
Gerrit simplifies Git based project maintainership by permitting any authorized user to submit changes to the master Git repository, rather than requiring all approved changes to be merged in by hand by the project maintainer.
Documentation
For information about how to install and use Gerrit, refer to the documentation.
