This should fix the crash when entering the freedom HQ elevator. It was
caused by a large number of prints, one for each process in the city
being killed by `check-for-rougue-process`, which would overflow the
print buffer. So I increased the print buffer.
Detecting buffer overflow here is hard because lots of things are
allowed to write to it, including the user's GOAL print methods. I added
a basic check that will assert when there's 1k or less space in the
buffer. It won't catch every overflow, but it would have caught this
one.
