max-cache-size doesn't work with 9.5.0b1

I have a somewhat loaded caching only nameserver, running FreeBSD/amd64 7.0.
I decided to try 9.5.0 just to see how well it goes, but it turned out
that its memory usage grows endlessly (OK, limited by the total VM space :).
I see this in top (the usage grows nearly every seconds, the machine
gets some thousands queries per sec):
PID USERNAME THR PRI NICE SIZE RES STATE C TIME WCPU COMMAND
16969 bind 5 96 0 727M 723M select 0 8:51 68.12% named.950
The relevant parts from the config (cache-size set to very low, just to
demonstrate the problem):
This is the case with and without ISC_USE_INTERNAL_MALLOC.
With 9.4.2 the memory usage does not grow above a given size:
17727 bind 5 97 0 131M 111M select 0 11:14 11.08% named.942
