Because I wanted to remove the libsas (mis-)feature and avoid to many boad
driver changes. Especially for a unmaintained big driver like aic94xx.

The task_collector mode (or "latency_injector", (C) Dan Willians) is an
optional I/O path in libsas that queues up scsi commands instead of
directly sending it to the hardware. It generall increases latencies
to in the optiomal case slightly reduce mmio traffic to the hardware.
