This commit enables compatibility of instrumentation-file-append-pid and
instrumentation-sleep-time options. It also requires keeping the
counters mapping between the watcher process and the instrumented binary
process in shared mode. This is useful when we instrument a shared
library that is used by several tasks running on the target system. In
case when we cannot wait for every task to complete, we must use the
sleep-time option. Without append-pid option, we would overwrite the
profile at the same path but collected from different tasks, leading to
unexpected or suboptimal optimization effects.
