How difficult is it to allow parallel compilation of code with the Rust stable and nightly channels?
<p>The default file-tree created by Cargo allows parallel compilation of release and debug builds as they are located in their own directories; <code>target/release</code> and <code>target/debug</code>, respectively.</p>

<p>How difficult is it to also allow parallel compilation of <code>stable</code>/<code>nightly</code>-compiler. For example using the directories </p>

<ul>
<li><code>target/debug/stable</code></li>
<li><code>target/debug/nightly</code></li>
</ul>

<p>I am aware it can be done with jails/containers, but I was hoping for a somewhat more Cargo-ish solution.</p>
