*disallow-scheduling*

This special variable is bound to t whenever multiprocessing scheduling is disabled. For example, the system binds this variable to t during the execution of the forms within a without-scheduling form.

This variable is read-only and should never be set or bound by user code. Examining the value of this variable is most useful when executing code that may operate in an asynchronous manner relative to multiprocessing.

See multiprocessing.htm for general information on multiprocessing in Allegro CL.
