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.
The documentation is described in introduction.htm and the index is in index.htm.
