High CPU and Stack Overflow

[tsmaeder]

Describe the bug

When starting up a self-hosting workspace, I get very high CPU. Profiling revealed that a lot of time was spent appending stuff to an output buffer. The "hosted-instance-log" output stream revealed a very large number of messages like this:

Extension-Host:RangeError: Maximum call stack size exceeded
    at DisposableCollection.get (/home/theia/node_modules/@theia/core/lib/common/disposable.js:65:23)
    at DisposableCollection.dispose (/home/theia/node_modules/@theia/core/lib/common/disposable.js:72:18)

This looks a lot like we're directly or indirectly adding a DisposableCollection to itself.
