- * - <b>maestro-set/maestro-set.cpp: Switch the system thread hosting our maestro</b>.
- * That's a very advanced example in which we move the maestro thread to another process.
- * Not many users need it (maybe only one, actually), but this example is also a regression test.
- *
- * This example is in C++ because we use C++11 threads to ensure that the feature is working as
- * expected. You can still use that feature from a C code.
