Is that your sentence?  Or could you point me to the source for further
reading?  I agree that the huge inbalance between the amount of
available memory and the amount of available file descriptors is a
problem.  But the sentence does not explain the details.  Is it the
consequence of Lisp running on a hosted operating system with those
constraints?  Did for example lisp machines have the same constraints?
Why?  Could EMFILE and ENFILE trigger gc and then retry open?  sbcl does
finalize file descriptors and iirc some schemes close them automatically
too.
