hyperactive dhclient?

[Robert Huff]

	Normally, I expect dhclient to run at startup and then
disappear into the background.
	Today - in the process of diagnosing other troubles - I ran
into this from top:

last pid: 48344;  load averages:  3.30,  2.85,  2.46    up 0+19:50:53  14:17:04
127 processes: 3 running, 122 sleeping, 1 zombie, 1 lock
CPU states: 42.4% user, 12.5% nice, 42.4% system,  2.7% interrupt,  0.0% idle
Mem: 146M Active, 22M Inact, 100M Wired, 2560K Cache, 60M Buf, 222M Free
Swap: 2048M Total, 310M Used, 1738M Free, 15% Inuse, 156K In

  PID USERNAME    THR PRI NICE   SIZE    RES STATE    TIME   WCPU COMMAND
  226 _dhcp         1 111    0  1528K   268K *Giant  31:04 12.74% dhclient


	Now I assume "*Giant" means the Giant Lock ... which is another
thing I've never seen before.  Not for dhclient, and not for
anything else.
	Gut reaction says this is not a good thing.  On the other hand
my gut reaction has often been wrong.  Is there a legitimate reason
for this much activity?  If not, how do I figure out what's broken?
	(I'm running

FreeBSD 7.0-CURRENT #0: Wed Jan  4 13:41:21 EST 20

	but this is as much a question about dhcp as it is about
any particular version.)
