Currently the number of "thread queues" is hardcoded at a value of 256. This affects all runmodes using these queues, most notably autofp. Autofp will be limited to 256 'detect' threads.

Given the advance of many-core systems, this may at some point be a limiting factor.

It appears the only limitation is the queue declaration, so moving to a dynamic way of creating queues would remove this limit.
