In order to run under memfault, the framework is first extended to handle running concurrent tests - i.e. multi-threading. (Not that this is a requirement for memfault, instead it shares a common goal of storing per-test data). To that end all the global data is moved into a per-test context and the targets are adjusted to avoid overlap on shared, global resources (such as output files and frame buffers). In order to preserve the simplicity of the standard draw routines, the context is not passed explicitly as a parameter to the routines, but is instead attached to the cairo_t via the user_data. For the masochist, to enable the tests to be run across multiple threads simply set the environment variable CAIRO_TEST_NUM_THREADS to the desired number. In the long run, we can hope the need for memfault (runtime testing of error paths) will be mitigated by static analysis. A promising candidate for this task would appear to be http://hal.cs.berkeley.edu/cil/.
