ETR_SHORT_SLEEP
This macro searches for a "sleep" function that has 1/1000 of a second accuracy. On some systems, this is known as nap() and on others usleep() / 1000. There are probably other functions like this defined in other system libraries, but we don't know how to search for them yet. Contributions joyously accepted. :)
