STACK OVERFLOW PROTECTION: To avoid having to check for stack
|
|
underflow after each pop operation (which can end up being
|
|
prohibitive in terms of costs), PS_ADDR should be set to
|

|
|
seldom have words requiring more than 3 items from the stack.

|
Then, at each "exit" call we check for stack underflow.
