Hi all

I just noticed something I did not expect... I had to purge two small 
images from te cache - they have a ttl of ten minutes.

I telnet into varnish and write

url.purge *varsel_oversigt.png
I get a 200

I write

url.purge *varsel_markering.*
I get a 200

I log out of telnetpromt

and notice that the "root-driven" varnishd is now in 100% cpu usage it has 
been there since (½ an hour).
There is no problem for the users (I think) as the "nobody-driven" varnishd 
serves them and only uses around 8% cpu.

What is varnishd using one whole cpu for ?
