pfctl -x fails on -current

Hi all,

  I'm running the OpenBSD 4.6 snapshot from June 26th and I can't get
pfctl(8) to set the debug level:

# pfctl -si | grep Debug
Status: Enabled for 0 days 01:37:04           Debug: Urgent
# pfctl -x loud
debug level set to 'loud'
# pfctl -si | grep Debug
Status: Enabled for 0 days 01:37:12           Debug: Urgent

  I've seen that there have recently been some changes in how the debug
level is set in pf_ioctl.c... is it still a work in progress? Am I
missing something?
  Thanks in advance!
  Cheers,

    Daniele
