This just adds the initial "workload", a call to libc's usleep(1000us)
function:
$ perf stat --null perf bench uprobe all
# Running uprobe/baseline benchmark...
# Executed 1000 usleep(1000) calls
Total time: 1053533 usecs
1053.533 usecs/op
Performance counter stats for 'perf bench uprobe all':
1.061042896 seconds time elapsed
0.001079000 seconds user
0.006499000 seconds sys
$
More entries will be added using a BPF skel to add various uprobes to
the usleep() function.
