Even for testing, 10 or 20s is a bit short.

It's not required to. The fact that the lease end time is sufficient
for both sides to know that the lease has expired.
DHCP-Release is used by a client that wants to explicitly end a lease
it no longer needs, before it's due end time. Some clients will do
this when the user tells them to shut down or sleep, most don't.
Also, you have sent this question to the BIND users list as well as
the DHCP users list. That is very bad etiquette, the query has no
connection whatsoever with BIND and you really should not clutter
lists with irrelevant noise like that.
