I just did an experiment, and test_apps is spending over half its time
(95 seconds that could be 40) redundantly clearing every stream before
every test. And some of those streams are _large_; the translators for
SubX and Mu use streams sizes pessimistically for the largest possible
program they can handle (1MB per segment).
A single test (the one in assort.subx) spends 24 seconds initializing 2
1MB-segments before processing a dozen lines of text in the blink of an
eye.
I'm not going to speed this up. But good to know.
