( u -- )

Wait at least u milliseconds.

The actual length and variability of the time period depends upon the implementation-defined resolution of the system clock and upon other system and computer characteristics beyond the scope of this standard.

A.10.6.2.1905 MS.

Although their frequencies vary, every system has a clock. Since many programs need to time intervals, this word is offered. Use of milliseconds as an internal unit of time is a practical "least common denominator" external unit. It is assumed implementors will use "clock ticks" (whatever size they are) as an internal unit and convert as appropriate.
