System.Posix.Signals should provide a way to set the SA_NOCLDWAIT flag
Since FreeBSD and OpenBSD don't conform to POSIX.1-2001 regarding the creation of zombie processes, “installHandler sigCHLD Ignore Nothing” just isn't enough to stop zombies from piling up. They do, however, support the SA_NOCLDWAIT flag to sigaction, and an interface for it would be useful to have.
