 /* This patch turns hard-coded usleep() usage into a VTIM_sleep() equivalent.
- *
- * Unfortunately, if a file contains the same usleep() call twice, each call
- * site will be substituted twice.
- *
- * This code:
- *
- *     usleep(10000);
- *     usleep(10000);
- *
- * Will turn into this:
- *
- *     VTIM_sleep(0.01)VTIM_sleep(0.01);
- *     VTIM_sleep(0.01)VTIM_sleep(0.01);
- *
- * Fortunately, it does not compile and cannot go unnoticed.
