A <code>BuildRequest</code> is a request to build a specific revision of the source
code (specified by a source stamp) on a single <code>Builder</code>. Each
<code>Builder</code> runs the <code>BuildRequest</code> as soon as it can (i.e. when an
associated buildslave becomes free). <code>BuildRequest</code>s are prioritized from
oldest to newest, and when a buildslave becomes free, the <code>Builder</code> with
the oldest <code>BuildRequest</code> is run.
<p>The <code>BuildRequest</code> may be mergeable with other compatible
<code>BuildRequest</code>s. Builds that are triggered by incoming Changes
will generally be mergeable. Builds that are triggered by user
requests are generally not, unless they are multiple requests to build
the <em>latest sources</em> of the same branch.
