I guess I have finally seen this complaint enough to investigate.

Consider this program:

#include <stdio.h>
int
main(int argc, char **argv)
{
  int i;
  for (i = 0; i < 100; i++)
    {
      FILE *f = fopen("/dev/null", "r");
      if (!f)
	break;
      printf("%d\n", i);
    }
  exit(0);
}

When I run it, I see numbers up to 99.  That means that there is no
20 open file limit, AFAICT.  Maybe this is just in recent snapshots.

If so, it will be fixed in the next release.
