E.g. commits 46d88d8dba56 and 2ba0b7497ce7 were only possible because I was seeing tests timing out in Power hosts when the 30 sec timeout was being enforced. A 120 second default timeout for the majority of the test cases is a long time. virschematest in this laptop I use takes 2.5 sec to complete. If I do something wrong in the code and now the test is now 4 times slower (10 sec) I will not be able to detect it (I'll need to start keeping track or something).

You'll have to run the test suit on your RasPi 2B to see that something went wrong because the timeout is better tuned to your RasPI than this laptop, but then the code is already upstream.

And the tests will get more complex and will naturally take longer to complete. Eventually this timeout might no be enough. Increase the timeout again?
