Module reaper 

The underlying system reaper.

There are two backends:

• signal, which waits for SIGCHLD.
• wait, which waits directly on a process handle.

“wait” is preferred, but is not available on all supported Linuxes. So we test to see if pidfd is supported first. If it is, we use wait. If not, we use signal.
