Most of these snippets are likely to have some env var that causes the data to hold constant, while the data will otherwise be likely to vary over time. This framework offers a way to test those snippets, by dropping the variable and an example value in the test/snippets/FOO.variable one-line file. Note that the test/snippets/syscall.c snippet is *not* expected to vary over time (or to differ when any given variable is set), so we simply don't add any test/snippets/syscall.variable file to avoid it being tested in this way.
