This isn't used yet, but will be for the new-style builders (VMs on GCE running the buildlet, started by the coordinator). From the code's comments: cleanUpOldVMs periodically enumerates virtual machines and deletes any which have a "delete-at" attribute having a unix timestamp before the current time. These VMs are created to run a single build and should be shut down by a controlling process. Due to various types of failures, they might get stranded. To prevent them from getting stranded and wasting resources forever, we instead set the "delete-at" metadata attribute on them when created to some time that's well beyond their expected lifetime, and then this is the backup mechanism to delete them if they get away.

The files in this directory constitute the continuous builder:
app/: an AppEngine server. The code that runs http://build.golang.org/
buildlet/: HTTP server that runs on a VM and is told what to write to disk
and what command to run. This is cross-compiled to all architectures
and is the first program run when a builder VM comes up. It then
is contacted by the coordinator to do a build.
builder/: gobuilder, a Go continuous build client
coordinator/: daemon that runs on CoreOS on Google Compute Engine and manages
builds (using the builder in single-shot mode) in Docker containers.
env/: configuration files describing the environment of builders and related binaries.
Many builders are still configured ad-hoc.
watcher/: a daemon that watches for new commits to the Go repository and
its sub-repositories, and notifies the dashboard of those commits.
If you wish to run a Go builder, please email golang-dev@googlegroups.com
To run a builder:
* Write the key ~gobuild/.gobuildkey
You need to get it from someone who knows the key.
You may also use a filename of the form .gobuildkey-$BUILDER if you
wish to run builders for multiple targets.
* Append your username and password googlecode.com credentials from
https://code.google.com/hosting/settings
to the buildkey file in the format "Username\nPassword\n".
(This is for uploading tarballs to the project downloads section,
and is an optional step.)
* Build and run gobuilder (see its documentation for command-line options).
