There was a problem hiding this comment.
We can implement getppid on windows, don't know why we do not have it.

Part of #117276.
Availability of process IDs is highly correlated with availability of processes, so moving the
getpidimplementations tosys::processmakes a lot of sense (and removes quite some code duplication). The only notable change here is on Hermit, which doesn't have processes but does havegetpid. But that always returns 0, so I doubt it is useful. If the change to a panic is problematic we could always copy the stub implementation and return zero ourselves (this also applies to the other single-process platforms).CC @stlankes @mkroening
