I think it is fine if this is an open problem but I would like more graceful failure. Isn’t it possible to catch this behavior and turn it into a lisp-level error?|

Emacs is limited by the limits of select, which supports a maximum of
FD_SETSIZE file descriptors, which on macOS is 1024
At least on macOS, itʼs possible to increase that value to eg 8192 by
setting FD_SETSIZE, which might alleviate this, but then you'd
probably run into the 'ulimit -n' maximum, so you'd have to remember
to increase that.
