Ok, I have only used capsicum a little so far, but I would expect:
pdkill on zombie to return EBADF - the file descriptor must be closed
if child exited.
parent dies: only kills pdfork child if actually last fd, you can pass
a pdfork fd to another process.
Also, I do miss a kqueue method to wait on pdfd, its odd that there is
EVFILT_PROC but not a filter to watch on pdfork fds.
Definitely worth documenting these cases.
