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), we give ourselves a nice 6
|
|
bytes buffer. 6 bytes because we seldom have words requiring
|
|
more than 3 items from the stack. Then, at each "exit" call we
|
|
check for stack underflow.
