Yep - I agree.

Two other gotcha's.  The kernal has a max number of open files variable,
it's worth checking that.  Then if you go for the setdtablesize() option
you'll need to check the max number of processes that can have more than
20 descriptors and also what the max number of descriptors is.  Then
you'll either have to re-write your code because the stdio library
has a max of 20 open files or you'll have to get the BSD4.3 stdio package
and build that.  I did the latter.
