Thanks for the interesting read. Skimming testing.sh I see that it uses
bash extensions and therefore each test script should be executed by bash.
Presumably, the extensions used in testing.sh belong to the (not yet well-
defined) set of sane extensions to be implemented in toybox's sh at some
point?
