It's system dependent. When I wrote my own Lua sleep() function (based
upon nanosleep()), I found that the minimum "sleep quantum" on Solaris to be
0.01 while on Linux, it was more like .0005. I found this out empirically,
but the clock_getres() function (available on Linux and Solaris) confirmed
this (when I found out about the function).
