Description

It would be like waitForProcess, except returning a statistics list.

On Linux/BSD, this is the wait4 system call.
On Windows, these can be extracted with GetProcessMemoryInfo/GetProcessTimes similarly to the exit code.
On Mac, wait4 returns the times, but getting memory statistics requires a tricky [Mach task info call](http://www.foldr.org/~michaelw/log/computers/macosx/task-info-fun-with-mach) which probably doesn't work on dead child processes (and I have no easy way of testing it).

Research direction

Start by reading the existing waitForProcess API and its platform-specific implementations. Compare the Linux/BSD wait4, Windows GetProcessMemoryInfo/GetProcessTimes, and macOS task-info approaches described here. Done means agreeing on a cross-platform statistics API and confirming its behavior for each supported operating system.
