Is that a problem? Fopen() and friends return the corresponding file handle
in the lower WORD of the positive LONG, or a negative error-message. But
even if it were a problem, I can always change the mask to 0x4000 (16k
opened files per process, still far away from the current 1024 limit).

Hmm. Thanks for this question, it reminded me of one post I saw when trying
to learn something about it:
https://mikro.naprvyraz.sk/mint/199801/msg00110.html. Back then I didn't
understand the question but now I do, and yes, it seems this was a
limitation of O_GLOBAL.

So allocating one special file descriptor for /dev/console per process
seems like a better solution I guess?
