Arguments: object
Returns t if object is a stack-group and returns nil
otherwise.
USE OF THIS FUNCTION 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 function is used only
by the non:os-threads model. The symbol naming this
function 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 function will not work.
The documentation is described in introduction.htm and the index is in index.htm.
