A "sleep" command, I would expect to sleep for a certain number of seconds,
for compatibility e.g. with terminal "sleep" command.
To keep this as "ms" granularity, how about making it explicit as a
"sleep_ms" command. Alternatively, how about adding a usleep command? [Not
sure "msleep" works, which is why I suggested sleep_ms instead]
