Precision isn't the thing I'm going for, just rough fractional seconds
(to test copying a 1 byte file 20 times a second to profile io rates
and cpu usage on an arm system, for example)

Agreeably, usleep is a moot point (and to implement nanosleep would
just be a fun example of it's use).

time msleep 128

real    0m0.129s
user    0m0.000s
sys     0m0.000s

Good enough.

Also, it turns out that some implementations of sleep allow fractional seconds.
