Add a test designed to generate contention on the taskq spinlock by using a large number of threads (100) to perform a large number (131072) of trivial work items from a single queue. This simulates conditions that may occur with the zio free taskq when a 1TB file is removed from a ZFS filesystem, for example. This test should always pass. Its purpose is to provide a benchmark to easily measure the effectiveness of taskq optimizations using statistics from the kernel lock profiler.
