*current-stack-group*

This variable always holds the stack-group that is currently executing. It is nil before the first stack-group-resume is done. This variable should be treated as read only.

USE OF THIS VARIABLE IS DEPRECATED.

Allegro CL has two models of multiprocessing, the :os-threads model and the non :os-threads model, so named because :os-threads is on the *features* list of versions that use it. This variable is used only by the non :os-threads model. The symbol naming this variable does not exist in versions using the :os-threads model. Conditionalize uses of this symbol in code that might be ported between versions with #-os-threads.

Note that in the future, all versions of Allegro CL may use the :os-threads model and code using this variable will not work.

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