CRITICAL F002: worker_pool from_raw_fd changed from 'raw: usize' to
'std::os::fd::RawFd' (c_int). A garbage 64-bit value can no longer
be cast to a valid i32 fd; the value can only have come from a
previously-validated fd (via IntoRawFd::into_raw_fd, libredox::Fd::raw,
or a similar source that went through the kernel's open-fd table).
CRITICAL progress: 12 of 13 original findings now addressed.
Remaining: F003 (scheme File ownership, 3 unsafe sites in
scheme/mod.rs around lines 183 and 195).
