How can I find out how many file handles the kernel can support?

One of our ultrix boxes is getting ready to be converted to NetBSD.  It
used to have trouble with too many ftpd's open at once, and they would
eventually suck up all the file handles.  We had to increase that by
raising maxusers.  What's the equivalent limit in NetBSD?
