Can't dump stacks larger than 200MB
When dumping stacks, we write the entire stack into memory to avoid
being bound by file I/O. If the stream grows to past 2 ** 28 bytes,
VisualWorks sends a signal which is trapped by the stack dumping
code, which is added to the stream, resulting in further signals,
resulting in infinite recursion.
