'Process Lasso', and 'Aloaha Sign'

Process Lasso

Intended to automatically adjust the allocation of CPU cycles so that system responsiveness is improved in high-load situations. It does this by dynamically temporarily lowering the priorities of processes that are consuming too many CPU cycles, thereby giving other processes a chance to run if they are in need. This is useful for both single and multi-core processors.
