[Dnsmasq-discuss] SIGUSR2 creates lease file, despite use of --leasefile-ro

On a Tomato USB router, which I believe runs Dnsmasq (v2.55) with the
--leasefile-ro option, which is documented as:
Completely suppress use of the lease database file. The file will not
be created, read, or written.
If you run:
# cat /var/tmp/dhcp/leases
cat: can't open '/var/tmp/dhcp/leases': No such file or directory
# killall -SIGUSR2 dnsmasq
# cat /var/tmp/dhcp/leases
#
So the file is empty, but does exist after receiving SIGUSR2 signal. Bug?
