I run my machine with kern.maxfiles=5120

I'm sure I could raise it much higher, but not necessarily.

The only time I ever ran up against the limit was when there was a bug 
in Nat's new wsbell code (which opened the /dev/audio to issue the 
"beep" tone, but never closed the device).  Otherwise I haven't hit it, 
and I'm always running large pkgsrc rebuilds and/or netbsd build, and 
always with many parallel jobs.  (I default to MAKE_JOBS=8 for pkgsrc, 
and -J 24 for release builds.)

So, I'm not against raising it, but we would need to have some specific 
value that would work on small (arm SOCs?) as well as large systems such 
as mine!  Perhaps some algorithmic calculation based on other system 
parameters?
