Block the current process for @var{Time} seconds. The number of seconds
must be a positive number, and it may an integer or a float. The Unix
implementation uses @code{usleep} if the number of seconds is below one,
and @code{sleep} if it is over a second. The WIN32 implementation uses
@code{Sleep} for both cases.
