The purpose of this test is to measure various Linux latencies
latconnect localhost - measures TCP/IP connection latency
lat_proc fork - latency to fork an identical process and have one exit.
lat_proc exec - latency to fork an identical process and run a program.
lat_proc procedure - latency to fork an identical process and ask the system shell to find a program and run it
lat_select tcp - latency to select 200 tcp file descriptors
lat_sem - semaphore latency
lat_sig install - latency to install a signal
lat_sig catch - latency to catch a signal
lat_tcp localhost - latency for a TCP server to localhost
lat_unix - interprocess socket communication latency
