core dumps again as well ...

[Peter Van Epp]

	I think there is a bug at least on FreeBSD: even if I specify the 
output file as ./argus.log it still writes it to /:

test4# argus_bpf -dJRw ./argus.log
argus_bpf[7472]: started

	and both times I kill -HUPed the lead process is core dumped:

test4# ps auxw |grep argus
root    7473  0.0  2.0  2364 1236  ??  Ss    1:47PM   0:00.12 argus_bpf -dJRw ./argus.log
root    7474  0.0  1.6  2136 1000  ??  S     1:47PM   0:00.05 argus_bpf -dJRw ./argus.log
root    7475  0.0  1.8  2272 1136  ??  S     1:47PM   0:00.04 argus_bpf -dJRw ./argus.log
test4# kill -HUP 7473

	but that may be because I killed a task rather than the process group
when I look at it, but then again maybe not:

test4# mv /argus_bpf.core /argus_bpf.core.2
test4# argus_bpf -dJRw ./argus.log
argus_bpf[7497]: started

test4# kill -HUP 7497
7497: No such process
test4# ps auxw |grep argus
root    7498  0.0  1.9  2340 1208  ??  Ss    1:57PM   0:00.03 argus_bpf -dJRw ./argus.log
