vm::*alien-stack-size*[Global Variable]

Size in words of the alien stack allocated for a thread. The alien stack is used by lisp code to hold stack allocated alien objects. Except on the x86 port, the alien stack is shared with the foreign stack. The size may be initialised upon startup by the -alien-stack-size command line argument.
