Actually this isn't a good idea because the fd might have been re-used for something else; so an error should be reported to make that bug-condition noticeable so it can be fixed.
Instead, bash should search all active CPROC variables for any file descriptors being closed explicitly, and undef the corresponding COPROC slot; that will prevent bash from calling close() on a previously-closed file descriptor.
