That is consistent with my own observations. On my desktop ASCII
machine the hard limit for nofile appeared to be set to an arbitrary
limit of 4096. Unfortunately I, too, have no clue by what mechanism
this limit is pre-configured.
Note, however, that you can set both the hard and soft limits to
the same value simultaneously in /etc/security/limits.conf by using
a '-' (hyphen) in the <type> field (second column); for example:
<username> - nofile 32000
