This is the maximum size, in bytes, that an individual trace file will
reach. Once this value is reached, the trace file begins to wrap using a "circular
buffer" algorithm. However, this takes a considerable amount of time, and
may significantly slow down execution speed once the file starts wrapping.
Therefore, leave this value at -1, except in circumstances where disk space
is at a premium.
Note: This is the maximum length of a single trace file.
If an application is run multiple times, or multiple applications are run,
then each generated trace file reaches this size.
