I don't see any reason for the behaviour you describe, especially connected
to the exec stack.

Are you sure that among those 10000 calls of Box, there aren't some (many
enough) that have more than 4 parameters? That could produce an operand
stack overflow. Also a missing parameter may lead to an operand stack
undeflow. Try inserting in the PS code lines like "count == flush" to
display the operand stack depth, so you'll see if it increases or not; you
may also use "countexecstack" instead of "count" to check the exec stack.
This also help locate the exact spot where the error occurs.

Other notes, not connected to the problem:
(1) Why "2 1 roll" and not "exch"?
(2) Level 2 has the "rectfill" operator that does the same thing as your
"Box" (with subtle differences that usually don't matter).
