				jillesUnsubmitted Not Done Inline Actions This needs `__returns_twice` like vfork/rfork/setjmp. If a `PD_VFORK` flag is added to `pdfork()` instead of adding `pdvfork()`, then `pdfork()` will need to be annotated. jilles: This needs `__returns_twice` like vfork/rfork/setjmp.

				jillesUnsubmitted Not Done Inline Actions The standard syscall stub will not work properly on x86 for this function. The child process pops the return address off the stack and if it is subsequently overwritten, the parent process will jump to nowhere. See for example `lib/libc/amd64/sys/vfork.S`. jilles: The standard syscall stub will not work properly on x86 for this function. The child process…
