CRM Package Deployer fails with the "DeleteHoldingSolution Timeout" message, if the deletion of the holding solution takes more than 2 minutes. Good news are, there is a way to fix this problem by forcing CRM Package Deployer to do the import in an asynchronous manner. It's documented on the PowerShellGallery page:

In the Importconfig.xml file: Add requiredimportmode as an option to force an async or sync import behavior for a given solution.
