9.3.44: `sleep'

`sleep .sec.'

Cause Gri to sleep for the indicated number of seconds, which should be a positive integer. This command is ignored if `.sec.' is zero or negative, and the value of `.sec.' is first rounded to the nearest integer.

Normally, this command is used only by the developer, as a way to slow down Gri execution, to allow easier monitoring for debugging purposes. Beware: it is tricky to kill a sleeping job!
