Add pollWithRusage to Subprocess
Summary:
I was looking for a way to get rusage of a particular pid because
getrusage isn't good enough since it records the rusage of all the children
that has been terminated (and waited for). Even though wait4 is marked as
deprecated, wait3 (the cousin of wait4) is still being used in places like
time. Furthermore, there is no suitable replacement to get rusage with wait*.
